Description

双重缓冲充气包装袋及其制造方法 Double buffering inflatable bag and a manufacturing method

技术领域 FIELD

[0001] 本发明涉及一种充气包装袋,是一种用于商品防潮、防震、防挤压、防冲击的充气袋包装材料。 [0001] The present invention relates to an inflatable bag, a commodity for moisture, shock, anti-extrusion, impact-resistant inflatable bag packaging material. 充气后可作物品包装填充材料使用,也可做物品包装箱内部六面防护垫用,更可以做物品外包装袋直接做成产品的零售包装。 Inflatable packaging article can be used after the filling material used, but also the internal article do hexahedral box with protective pad, the outer bag can also be made directly to the retail items packaged product.

背景技术 Background technique

[0002] 许多商品特别是电子产品、玻璃制品等易碎产品在仓储、运输时需要采用发泡聚苯乙烯、聚乙烯气泡垫等垫在包装箱和商品之间,或者用发泡材料直接包装商品,以达到防震、防挤压、防冲击效果,防止商品在储运时损坏。 [0002] Special many electronic products, glass products and other fragile products in storage, transport need of expanded polystyrene, polyethylene, bubble wrap and the like cushion between the box and the goods or packaging the foaming material is directly goods, in order to achieve shock, anti-extrusion, anti-shock effect, to prevent product damage during storage and transportation. 传统的发泡聚苯乙烯(EPS)及聚乙烯泡沫塑料(EPE)类制品,必须在生产厂家发泡成型或经过加工处理后才能运输给用户使用,成型后的泡沫塑料体积庞大非常不便于运输及仓储。 Traditional expanded polystyrene (EPS) foam and polyethylene (EPE) type products, foam molding must be processed before or after transportation to users at the manufacturer, the foam volume after molding very easy to transport bulky and warehousing. 为了方便运输而开发的现场发泡类材料,主要是利用聚氨酯泡沫塑料制品,在内容物旁边发泡膨胀并形成保护模型。 In order to facilitate the transport and the development of foam-like material, mainly using polyurethane foam products, foaming expansion and formed alongside the content protection model. 但是,材料的价格相对较高并对现场的设备有一定要求,同时在工人效率及工作强度要求上不适合大规模流水线产品如电子产品的内包装。 However, the relatively high price of materials and equipment in the field there are certain requirements, but does not fit on worker efficiency and strength requirements of large-scale assembly line work such as product packaging of electronic products. 同时,发泡聚苯乙烯(EPS)类制品的诸多弊端日显严重,已经成为人皆恶之的“白色污染”。 Meanwhile, many drawbacks day expanded polystyrene (EPS) type products is considerably severe, everyone has become evil "white pollution." 相对只在运输环节短期使用的缓冲产品,永久性聚苯发泡包装的废弃物处理给环境带来严重污染,如燃烧会产生有毒气体,而堆埋因不能腐蚀而产生地质结构的破坏。 Buffer products are relatively short-term use only in transport links, permanent polystyrene foam packaging waste to the environment serious pollution, such as the burning will produce toxic gases, while the heap buried because they could not produce corrosion damage to the geological structure.

[0003] 近年来出现的一种改进的充气袋包装制品,包括一气袋并具有一单向逆止阀,通过单向逆止阀向气袋内充气并防止袋内气体回流漏出,充足气的气袋具有很好的吸收冲击能量的缓冲效果,用充气后的气袋包裹商品或填充在商品与包装箱之间,以保护商品不被损坏。 [0003] An improved inflatable bag packaging products in recent years, including a bag and having a one-way check valve, the pneumatic bag and preventing backflow of gas from leaking into the bag through the one-way check valve, sufficient gas the bag having a good cushioning effect to absorb the impact energy, with the bag after inflation wrapped goods or goods filled between the box and to protect the goods from damage. 这种充气袋生产和运输时未充气,只有在包装商品时才充气,而且用完后可回收利用,因此克服了传统发泡材料的前述缺点,材料采用塑料薄膜,还具有防潮效果。 Such uninflated inflatable bag production and transportation, only inflated when packaged goods, and recyclable after use, thus overcoming the aforementioned drawbacks of traditional foamed material, plastic film material, further has the effect of moisture. 如CN1903675A,这种充气袋一般是由两张宽塑料薄膜和两张窄塑料薄膜组成,两张宽塑料薄膜置于表层,两张窄塑料薄膜置于中间层,经过热封使两张宽塑料薄膜形成可充气的袋体,而两张窄塑料薄膜则通过在相向的表面印刷耐高温油墨,被热封与两张宽塑料薄膜粘合在一起,印刷油墨的部分不能热封从而在该处形成既可分离形成进气通道又可贴合形成气密效果的单向逆止阀。 As CN1903675A, that dunnage bags typically by two wide and two narrow plastic films composed of a plastic film, a plastic film is placed two wide surface, a narrow two plastic films placed in the middle layer, so that after heat sealing two wide plastic film-forming inflatable bag body, and two plastic films through narrow the facing surface of the printed ink temperature, are bonded together with two heat-sealed plastic film width, can not be heat-sealed portion so that the printing ink where forming a one-way check valve can turn intake passage formed separately bonded to form an airtight effect. 这种充气袋可作为减震垫使用或填充在商品与包装箱之间,或者包裹商品,也可以进一步经过不同折叠和局部热封,形成在充气后形成可直接套在商品外部的包装袋。 Such inflatable bag may be used as a cushion between the product and the filling or packaging, or wrapping goods, may be further subjected to various heat-sealing the folded and partially formed in the outer sleeve may be directly formed merchandise bags when inflated.

[0004] 然而,对于一些精密电子产品或者一些玻璃等易碎产品来说,有时具有较高的抗冲击防震要求,采用一层充气袋,由于起缓冲作用的气柱是贴在商品表面与商品接触,冲击能量仍然有一大部分会通过直接接触的气柱传递给商品,因此较大的震动或冲击仍然对商品造成一定的危害,甚至会压扁局部气柱而直接冲击到商品。 [0004] However, for some sophisticated electronic products glass or some other fragile products, high impact shock may request use of one inflatable bag, the air column due to the dampening effect is affixed to the surface of commodities and commodity contacts, there are still a large part of the impact energy is passed to the product by direct contact with the air column, and hence more vibration or shock still cause some harm to the merchandise, and even crushed directly impact local air column to the commodity. 为提高缓冲效果,虽然可以采用多层充气袋包装商品,但成本高,包装时间和充气时间较长。 In order to improve the cushioning effect, although the inflatable bag multilayer product may be employed, but the high cost and long time packaging and filling time.

[0039] 在外层袋子100靠近袋子底部的两侧边缘在一定距离内设置有侧开口,以使外层袋子在充气后设置有开口的部分如图2中下部那样向外膨胀。 [0039] disposed at a distance on both sides of the outer edge of the bag near the bottom of the bag has a side opening 100 to the outer layer of the bag is provided with an opening section when inflated to expand outward as shown in FIG 2 in the lower part. 为便于理解“侧开口”的设置,结合图3所示,图3是用于形成外层袋子100的薄膜材料即充气塑料夹膜,将一张图3所示充气塑料夹膜沿图中折线36进行对折,对折后通过充气塑料夹膜两侧自由边缘处的封边热合线31进行局部热合,便可将对折后的充气塑料夹膜上下层粘合在一起成为两侧闭合的充气塑料夹膜筒,从图3中可以看出热合线31长度约为充气塑料夹膜长度的1/4左右,因此对折后按图中所示方向的来看其下半部两侧自由边缘未被热封,使得对折后两层充气塑料夹膜在该区域两侧是有开口的结构,成为一种下半部具有侧开口的外层袋子结构。 To facilitate understanding of "side opening" is provided, in conjunction with FIG. 3, FIG. 3 is a thin film material for forming the outer layer of the bag 100, i.e., inflatable plastic film clip, the one shown in Figure 3 inflatable plastic film interposed along broken line in FIG. 36 fold, folded edge of heat wires at both sides of the free edge of the film is formed by a plastic clip inflator 31 locally heat, will be inflated after the plastic can be folded together into a bonding underlayer film interposed inflatable plastic clip is closed on both sides membrane cartridge, it can be seen from figure 3 the length of the heat seal line 31 about the inflator sandwiched plastic films about 1/4 of the length, so the direction shown in the lower half view of its free side edges are not folded heat seal, so that the folded layers of inflated plastic film sandwiched on both sides in the region of a structure having an opening, into a lower half of the bag structure having an outer layer of the side opening. 这样在向充气塑料夹膜内的条形充气室充气时,空气压力使得外层袋子100会如图2所示方式向外膨胀从开口处张开,使得该部分气柱在图中竖向上如图所示超过上部。 When the strip so that the inflatable plenum plastic film sandwiched inflation, air pressure such that the outer layer of the bag 100 shown in FIG. 2 will bulge outwardly flared from the opening, such as the portion of the vertical air column in FIG. beyond the upper shown in FIG.

[0040] 为形成图2所示的T形造型,如图3所示,外层袋子100是由一张充气塑料夹膜沿与条形充气室垂直的方向沿对折线36对折构成,在靠近外层袋子底部附近每侧设置有三道横向热合线32,即在对折线36两侧对称各设置了的三道横向热合线32,横向热合线32在每一条形充气室处其长度小于条形充气室13的宽度,以使热合线32两端与条形充气室13边缘保留一定通气通道。 [0040] To form the T-shape shown in FIG. 2, as shown, the bag 100 is a direction of the top film along with a strip of a pneumatic plenum plastic clips along the three pairs of vertical fold line 36 pairs folded configuration, in close outer pouch is provided near each side of the bottom three lines transverse heat seal 32, i.e. the fold line 36 symmetrically on both sides of each set of three transverse heat seal line 32, the line 32 is less than the transverse heat sealing bar in each of the bar at which plenum length the width of the plenum 13 so that the edge 13 and the heat wires 32 at both ends of the strip to retain a certain venting plenum passage. 这样在充气时如图2所示,该部分会在热合线32处弯折,通过控制三道热合线32之间的间距,则能形成图2所示T形结构:底部为水平气柱排列的基底部104,两侧的竖向气柱排列成的侧壁部103、105,两侧的斜气柱排列的斜壁部102、106 ;且各部气柱由图3可以看出是连通的,正常情况下能够保持相同的空气压力。 2 Thus, the portion of the heat will be bent wires 32 when inflated, by controlling a three line spacing between heat seal 32, it is capable of forming a T-shaped structure as shown in FIG. 2: the bottom of the column is aligned horizontally the base portion 104, side wall portions arranged on both sides of the vertical column 103, 105, obliquely inclined wall portions 102, 106 arranged on both sides of the air column; column, and each part can be seen from FIG. 3 is a communication , under normal circumstances, can maintain the same air pressure. 而内衬辅助薄膜如图1、2所示是悬在外层袋子100内。 The auxiliary film liner shown in FIG. 1 and 2 the bag is suspended within the outer layer 100. 这样当有沿基底部104垂直方向的冲击产生时,力和能量传递方式是由基底部104向侧壁部103、105,以及斜壁部102、106,再沿上部的直壁部一直传递到物品放入口后,再经过辅助薄膜传递才能到达商品300,传递路径长而且方向不断改变,绝大部分冲击能量先不断被外层袋子气柱内的空气和塑料薄膜吸收分解掉一次,再收辅助塑料薄膜吸收分解一次,从而起到多重缓冲效果,更好的保护商品不伤损坏。 Thus when impact in the vertical direction along the base portion 104 to generate, force and energy transmitted by way of the base portion 104 to the side wall portions 103, 105, 102, 106, and inclined wall portion, and then along the straight upper wall portion has been transferred to the after the article into the opening, and then passed through the auxiliary film 300 to reach the goods, and transfer direction changing path length, most of the impact energy to be constantly in the air and an outer layer of plastic film bags once broken down the absorption column, and then close decomposing a secondary absorbent plastic film, which play multiple cushioning effect to protect the goods better not to hurt the damage. 同样,如图2所示将两个本发明的双重缓冲包装袋套在商品300上,由于该部分向外膨胀,商品在与侧壁垂直的方向(图中水平方向)仍然是悬空的,受到震动的冲击首先是作用于侧壁部103或105,然后再通过斜壁部102或106传递到上部的直壁部后才能够达到商品,传递过程中大部分能量首先被侧壁103、106部吸收,然后再吸斜壁部102、106吸收,最后还要通过离商品最近的另一直壁部吸收,从而很快衰减,所以该实施例在各方向上都能够获得较好的保护效果。 Also shown in Figure 2 the two dual air bag of the present invention is set in the commodity 300, since the outward expanded portion, the side wall of goods in a direction perpendicular to the (horizontal direction in FIG.) Is still suspended by the shock vibration is applied to the first side wall portion 103 or 105, and then transmitted through the inclined wall portion 102 or 106 to an upper portion of a straight wall can be achieved before product, most of the energy transfer process is first sidewall portion 103, 106 absorption, and then suck the inclined wall portions 102, 106 absorbing and, finally, from the goods by the other wall portion has been recently absorbed so rapidly decay, so this embodiment can be obtained in each direction are better protective effect.

[0041] 另外,采用本实施中条形充气室的走向,在按图中所示方向放置时,由于气柱是直立,承压效果比气柱水平环绕效果好,更有利于对商品的悬空支撑。 [0041] Further, in the present embodiment to the plenum bar, when placed in the direction shown, since the upright column, the pressure level of the air column surround effects better than effects, is more conducive to product dangling support. 更重要的是,热合线32长度小于条形充气室宽度,使热合线32两端与条形充气室边缘即热合线33之间保留一定通气通道,使空气能够通过该部位给整个条形充气室充气和形成平衡气压,不但使得包装袋两承压面空气压力相同,而且该热合线32处变小的空气流通流道具有减压节流作用,在一侧受到猛然冲击时气体不会一下被迅速压到另一侧,避免气柱迅速被压扁直接冲击到内部的商品,同时又有部分气体可以进入另一侧又避免该受冲击侧气柱内压力过高而使该侧充气室爆裂。 More importantly, the length of the heat wires 32 is less than the width of the stripe-shaped plenum, so that both ends of the heat wires 32 and the edge strip plenum i.e. reserve a ventilation channel between the heat wires 33, so that the air can be inflated through the strip to the entire site the pneumatic pressure balance chamber formed, so that only the same two bags air pressure bearing surface, and the heat seal line 32 becomes a small air flow channel has a throttle effect under reduced pressure, when subjected to a side impact gas does not suddenly look It is quickly pressed to the other side, to avoid direct impact column quickly crushed into the interior of the product, while another portion of the gas may enter the other side by the impact and avoid the high pressure side of the column side of the plenum burst.

[0042] 充气塑料夹膜为如图3和图4所示,两张宽塑料薄膜11、12置于表层和两张窄塑料薄膜21、22置于中间层,经过热封形成的具有多个条形充气室13的结构,每一条形充气室13通过所述两张窄塑料薄膜21、22形成的自吸附单向逆止阀与笛形充气总通道7相通;其中充气室13是由宽塑料薄膜11、12形成室壁。 [0042] The pneumatic clamp plastic film shown in FIGS. 3 and 4, two plastic films 11, 12 wide and two narrow surface positioned plastic films 21 and 22 placed in the middle layer, having a plurality of formed through heat-sealing bar plenum structure 13, each of the bar from suction plenum 13 and one-way check valve 7 piccolo pneumatic passage communicating total 21 formed by the two narrow plastic film; wherein the plenum 13 is wide plastic films 11 and 12 formed in the chamber wall. 每一条形充气室13通过两张窄塑料薄膜21,22在进排气端形成的自吸附单向逆止阀与笛形充气总通道7相通。 Each of the bar from the suction plenum 13 through the one-way check valve and the narrower flute two plastic films 21, 22 formed in the end of the intake and exhaust passage 7 communicates the total inflator. 笛形充气总通道7也是在两张宽塑料薄膜11、12之间形成,由于该总通道与各条形充气室方向垂直且对应各条形充气室方向均有能够使空气流通的通道,类似笛子的笛孔一样,因此称为笛形充气总通道。 A flute is inflated total channel 7 between the two plastic films 11 and 12 are formed wide, since the total channel with each stripe corresponding to the plenum and a direction perpendicular to the direction of each stripe are capable of plenum air flow passage, similar to the as flute flute holes, so called pneumatic flute total channel. 这样这种可充气塑料夹膜如图4所示,通过热合在两张宽塑料薄膜11、12上边缘的笛形充气总通道7,向笛形充气总通道7充气,空气压力使各自吸附单向逆止阀中贴合在一起的窄塑料薄膜21、22分离以形成通路,空气即可进入各条形充气室13,条形充气室13膨胀形成气柱,以保护商品。 Such a film Such inflatable plastic clip shown in Figure 4, by heat sealing the inflator flute total channel width of the edge on the two plastic films 11, 12, 7, to inflate the inflatable flute total channel 7, so that the respective suction air pressure alone plastic film to narrow the check valves 21 and 22 bonded together to form separate passages, each bar can enter the air plenum 13, the plenum bar 13 expansion column formed to protect the merchandise. 停止充气在两张窄塑料薄膜21、22之间自吸力以及充气室内气体压力共同作用下,两塑料薄膜21、22又重新贴合在一起,将进气通道关闭使空气不能泄漏,压力越高贴合越紧。 Stop inflation between two plastic films 21, 22 narrow from the lower plenum and a suction gas pressure together, two plastic films 21, 22 are again bonded together, the intake passage is closed so that air does not leak, the higher the pressure more tight fit. 利用充气后形成的气柱吸收冲击能量,达到非常好的减震和保护商品的效果。 Inflated using air column formed after absorbing impact energy, achieve very good shock absorption and protection of goods.

[0043] 为了提高自吸附单向逆止阀密封效果,构成单向逆止阀的两张窄塑料薄膜采用自吸附极性塑料薄膜,如图5所示,·是在PE基材6的一侧面复合有自粘层5,形成单面自吸附膜材料。 [0043] In order to enhance the self-sealing effect of adsorption of the one-way check valve, two narrow plastic film using one-way check valve from adsorbing polar plastics film, as shown in Figure 5, - is a base material 6 in the PE self-adhesive side of the composite layer 5, a one-sided self adsorption film material. 自粘层是在EVA中添加有马来酸酐接枝的PE。 EVA is added to the self-adhesive layer has a maleic anhydride grafted PE. 采用一层PE基材一层自粘层为最基本的具有吸附性的极性膜材料结构。 PE substrate using one self-adhesive layer is a layer of membrane material polar basic structure with adsorption. 这种结构由于用量较少的极性原料是在基材一侧表面复合,极性材料分布均匀,因此吸附力均匀有利于提高密封效果,同时该侧面极性强也有利于两极性薄膜以极性面相对时吸附力好,同样提高密封效果。 This structure due to less amount of the polar material at the surface side of the composite substrate, a uniform distribution of the polar material, and therefore a uniform suction force help to improve sealing effect, while the strongly polar side also help to bipolar electrode film when the suction force is relatively good surface properties, the same improve the sealing effect. 由于马来酸酐接枝的PE极性优于EVA,通过调整其含量可以调整自吸附薄膜表面吸附力大小。 Since the polarity of PE grafted with maleic anhydride superior to EVA, the content thereof can be adjusted by adjusting the film from the suction surface of the suction force magnitude.

[0044] 进一步地,PE基材也可以采用多层复合材料,如图5所示,由与自粘层5复合的一侧起依次为LDPE层4,HDPE层或MLDPE层3,LDPE层2,LDPE+TNPP构成的防老化保护层I。 [0044] Further, PE multilayer composite substrate may be employed, as shown in FIG. 5, starting from one side of the self-adhesive layer 5 of the composite were LDPE layer 4, HDPE layer or layers. 3 MLDPE, LDPE layers 2 , aging protective layer made of LDPE + TNPP I. 其中HDPE层或MLDPE层3由于材料强度、刚性高于LDPE,因此能够使这种极性膜材料具有适度的刚性,使膜平整不易起皱,有利于后续耐高温油墨的精确印刷和分切,以及两层极性膜材料构成单向逆止阀自吸附时平整贴合无水印。 Wherein the layer of HDPE or MLDPE layer 3 due to the material strength and higher rigidity than LDPE, it is possible to make such a film material having a polarity appropriate rigidity, the film is difficult to wrinkle formation, subsequent high temperature conducive to accurate printing ink and cutting, and a two-layer film material constituting the flat polar one-way check valve attached to the self-adsorptive bonding without watermark.

[0045] 最外层采用LDPE+TNPP复合层,使用少量的TNPP可以达到改善表面与空气接触时耐氧化老化作用。 [0045] The outermost layer LDPE + TNPP composite layer, can be achieved using a small amount of TNPP oxidation resistant surface to improve the aging effects when in contact with air. 同样,在自粘层5内也添加抗氧剂,采用极性较好的酚类抗氧剂,添加量为整个极性膜材料总质量的0.5-1%。 Also, in the self-adhesive layer 5 is also an antioxidant, a phenolic antioxidant employed is preferably a polar, added in an amount of 0.5-1% of the total mass of the polarity of the entire film material. 由于极性膜材料只是表面与空气接触,本发明只有两最外层添加抗氧剂,能够达到在使用较少量抗氧剂时较好的抗老化效果。 Since the polarity of the surface of the film material is only in contact with the air, only the outermost layers of the present invention the addition of antioxidants, anti-aging to achieve better results when using a relatively small amount of antioxidants. 更特别的是,如果这种膜材料未被回收而遗弃,在环境中表面含抗氧剂的部分老化后,其内部塑料老化速度会较快,降解增速有利于减少对环境的危险时间。 More particularly, if such a film material is not recovered but abandoned, antioxidant-containing surface of the rear portion of aging in the environment, which the inner plastic aging rate will be faster degradation time reduce the risk of growth conducive environment.

[0046] 这种复合膜采用多层共挤复合,产品中各组份的含量通过原料用量来加以控制,因此本发明原组份含量是按原料比例来计算,而不是按各层中比较计算,将更有利于生产控制。 [0046] Such co-extruded composite multi-layer composite film, the content of each component in the product to be controlled by the amount of starting material, thus the present invention is a component of the original group content is calculated according to the ratio of raw materials, rather than the more layers in terms of will be more conducive to production control. 本发明中,自粘层I中EVA用量占整个极性膜材料总质量的2%_4%,马来酸酐接枝的PE占整个极性膜材料总质量的0.5%-1%,酚类抗氧剂占整个极性膜材料总质量0.3-1%。 In the present invention, the self-adhesive layer I _4% 2% of the total mass of the whole amount of the EVA with a polar film materials, maleic anhydride grafted PE 0.5% to 1% of the total mass of the polarity of the entire membrane material, phenolic antioxidant the total mass of the entire oxygen agent comprises 0.3-1% polar membrane material. 所述HDPE层或MLDPE层中HDPE或MLDPE用量为整个极性膜材料总质量的0.2-0.5%。 The layer of HDPE or HDPE or MLDPE MLDPE layer in an amount of 0.2-0.5% of the total mass of the polarity of the entire film material. TNPP占整个极性膜材料总用料质量0.5-1%。 TNPP the total polar material film mass 0.5-1% of the total material.

[0047] 为提高密封效果,如图4所示,在两张所述窄塑料薄膜21、22中,构成内外部空间阻隔层的一片极性膜材料22的厚度是另一片极性膜材料21厚度的100%-135%,增厚的阻隔层更有利于提供密封效果。 [0047] In order to improve the sealing effect, as shown, the narrow two plastic films 21, 22, the inner space constituting the outer barrier layer 4 thickness of a polar film material 22 is a film material further polar piece 21 100% -135% of the thickness of the barrier layer is thickened more effective for providing a sealing effect.

[0048] 本实施例中的这种双重缓冲包装袋,可以采用下面的方法由塑料薄膜通过热合制造而成: [0048] This double air bag of the present embodiment in the embodiment, the following method may be employed by the plastic film is manufactured by thermal bonding:

[0049] (I)参照图3和图4所示,由两张尺寸较宽的宽塑料薄膜11、12和两张较窄的具有内层相互吸附性能的极性窄塑料薄膜21、22组成。 [0049] (I) shown in FIG. 3 and, by the size of the two plastic films 11 and 12 wider and the width narrower two plastic films 21, 22 having a narrow inner polar adsorption properties of each composition 4 . 窄塑料薄膜21、22采用图5所示复合膜,这种复合膜可通过共挤吹塑形成。 Narrow plastic film composite membrane 21 shown in FIG. 5, the composite film may be formed by coextrusion blow molding. 将两张宽塑料薄膜11、12分别设置在窄塑料薄膜21、22的两边表层,窄塑料薄膜21、22设置在两张宽塑料薄膜11、12中间,且短于宽塑料薄膜11、12—定的距离,以便在其上部由宽塑料薄膜形成充气总通道7,按图1中所示相对位置尺寸关系设置好; The width of two plastic films 11 and 12 are respectively provided at both sides of the narrow surface of a plastic film, the plastic film 21, 22 21 and 22 narrow is provided in the middle of two plastic films 11 and 12 wider and shorter than the width of the plastic film 11,12 predetermined distance to form a pneumatic total channel width of the plastic film 7 in its upper set position in relative size relationship shown in Figure 1;

[0050] (2)单向逆止阀的形成:首先通过模具沿热合线44将极性塑料薄膜21、22与上表层塑料膜11按单向逆止阀充气通道热封位置要求热封在一起,形成空气通路和单向逆止阀。 [0050] (2) form a unidirectional check valve: firstly through a die 44 along the heat seal lines 21 and 22 and the polarity of the plastic film on the surface of the plastic film 11 by a one-way check valve pneumatic channels required heat sealed pouches together, forming an air passage and the one-way check valve.

[0051] (3)条形充气室形成:然后通过模具将宽塑料薄膜11、极性窄塑料薄膜21、22和宽塑料薄膜12根据充气室位置按照热合线33的位置同时热封在一起,形成每个气室之间的隔断,同时形成逆止阀开启热封点40。 [0051] (3) bar plenum formed: then through a die having a width of plastic film 11, 21, 22 and the polarity of the narrow width of the plastic film 12 The plastic film according to the position of the plenum heat position line 33 heat-sealed together at the same time, each partition is formed between the air chamber, while forming a heat-sealable check valve opening point 40. 由于极性塑料薄膜21、22之间有耐高温的印刷油墨层37的存在,而且通过模具已经将窄塑料薄膜21、22与上表层宽塑料薄膜11热封在一起,所以模具对热封点40部位可以一次同时将极性塑料薄膜21与塑料薄膜11热封在一起,将极性塑料薄膜22与塑料薄膜12热封在一起。 Because the plastic film 21 between the polarity of the temperature of the printing ink layer 37 is present, and through a die 21, 22 of plastic film has narrow width and the upper surface of the plastic film 11 heat-sealed together, the heat sealing die point 40 while the site may be a polar heat-sealed plastic film 21 and plastic film 11 together, the polarity of the plastic film 22 and plastic film 12 heat-sealed together.

[0052] (4)笛形充气总通道的形成:再再经过模具对热合线39、42、43的位置同时热封,这样就形成了笛形空气通道7和隐形热封通道K (由于有耐高温印刷油墨而不能粘合为一体),热合线39的作用是在注入压缩空气时,能够使极性塑料薄膜21和22在开启热封点40处能够迅速的打开,形成一个空气流通道,提高空气注入的效率。 [0052] (4) Formation of the flute-shaped inflatable total channel: amassing position of the mold after thermal bonding wire 39,42,43 while the heat seal, thus forming an air passage 7 and the flute invisible heat seal channel K (because printing ink temperature can not be integrally bonded), the action of heat wires 39 are in compressed air is injected, it is possible to make the polarity of the plastic film 21 and 22 are heat-sealed at the opening point 40 can be quickly opened to form an air flow path to improve the efficiency of air injection.

[0053] (5)在两张宽塑料薄膜11、12尾端经过模具沿热合线34进行横向热封,就形成了多个并列排放的可存放空气等介质的条形充气空间,形成可充气塑料夹膜,但这种片状结构只适用于填充或包裹商品。 [0053] (5) in the two films 11 and 12 wide plastic through a die trailing end 34 along a transverse line of heat sealing, to form a stripe-shaped plenum medium such as air can be stored side by side a plurality of, forming an inflatable plastic film clip, but this only applies to the sheet-like structure is filled or wrapped goods. 要想形成比较完整的袋形结构直接包装商品,还需要进一步处理。 To form a relatively complete configuration directly pouch packaged goods, require further processing. 当然,根据需要选择性地沿横向热合线32进行热封以形成T形结构。 Of course, if necessary to selectively heat-sealed transversely heat sealing line 32 to form a T-shaped configuration.

[0054] (6)内衬辅助薄膜200的热合:将短于可充气塑料夹膜的内衬辅助薄膜200结合图2所示方式使其的两端分别与可充气塑料夹膜两端通过热封线41、35热合,使其相互粘 [0054] (6) lined with heat auxiliary film 200: 200 ends shorter than the binding plastic film clip inflatable liner auxiliary film shown in FIG. 2, respectively, so as to clamp both ends of the plastic film inflatable by heat heat seal line 41,35, so that mutual adhesion

合在一起; combine together;

[0055] (7)外层袋子100的形成:将经过一系列热封后形成的具有多个条形充气室排列而成的可充气塑料夹膜,连同内衬辅助薄膜沿对折线36对折,沿自由边边缘至少在靠近外层包装袋物品放置口的部分在预定的封边热合线31位置进行二次热封,形成靠近物品放入口400 —端两侧自由边缘热封而靠近底部两侧自由边缘有侧开口的外层袋子100。 [0055] (7) forming the outer layer of the bag 100: arrayed inflatable plastic film having a plurality of strip-shaped clip plenums through a series of heat-sealed to form, together with the auxiliary film lined along fold line 36 pairs of folding, free edge portion along an outer edge of at least near the mouth of the bag items placed the secondary heat sealed at a predetermined position 31 edge heat sealing line formed near the mouth of items into 400-- heat sealing both side ends of the free edge near the bottom two an outer layer of the bag-side free edge of the side opening 100.

[0056] 实施例2 [0056] Example 2

[0057] 与实施例1不同的是,在外层袋子靠近袋子底部的两侧边缘在不预留有侧开口,全部通过二次热封形成三面封闭的外层袋子,如图6所示,这种实施方式形成的是在外层袋子100内部有悬空的内衬辅助薄膜200,上部为物品放入口400,结构简单,对于袋子底部的冲击能量是由底部沿外层袋子100到物品放入口的方向传递,再经过内衬辅助薄膜200传递商品,虽然缓冲效果略低于实施例1的方式,但仍然比仅用外层袋子100直接包装商品的防护效果要好的多。 [0057] Example 1 is different from both side edges of the bag near the bottom of the bag in the outer layer is not reserved for a side opening, closed on three sides are all formed by the second outer heat-sealing the bag, as shown in Figure 6, which embodiment species formed is suspended auxiliary film liner 200 inside the outer layer of the bag 100, an upper portion of the article into the opening 400, a simple structure, impact energy to the bottom of the bag is placed along the bottom of the bag 100 to the outer opening article transfer direction, and then passed through the liner auxiliary film product 200, while the buffering effect is slightly lower than in Example 1. the embodiment, only the outer layer of the bag 100 but still packaged goods direct protective effect much better than. 充气室13形成的气柱是竖向设置的以提高竖向承压能力。 Column plenum 13 is formed in order to improve the bearing capacity of vertically disposed vertically.

[0058] 实施例3 [0058] Example 3
