Abstract
The production method of folded soft packaging bag includes the main following steps: utilizing a forming machine to expand the bottom portion of the soft packaging bag whose bottom is sealed and make it into quadrangular form; upwards folding the mouth-sealed portion for sealing every corner of the four corners respectively along side surface to main front side, and form a flat bottom on the basis of said quadrangular form; die-pressing and setting so as to obtain the invented flat-bottom soft packaging bag like packaging box. Said invention is applicable to make any soft packaging bag.
Description
The present invention relates to a kind of method of making flexible packaging, especially a kind of making has folding soft packaging method.
Present packaging series mainly contains two big classes, and a class is a rigid package series, and as packings such as box classes, it is smooth that this type of packing generally has the bottom, can uprightly deposit, but can not be self-styled, package encapsulation poor performance, unfavorable guaranteeing the quality.Another kind of then is flexible packaging series, as packings such as bag classes, this type of flexible packaging since self distinctive character make its have can be self-styled and transparent etc. advantage, and good seal performance, help damp proof guaranteeing the quality, cost is low, thereby has obtained the widespread use of packaging industry, but its face shaping can't as box-packaged be accomplished still that owing to self characteristics relative bottom is smooth and can steadily stand up, and is relative with aesthetic utility inferior to the displaying of product.Can make existing flexible packaging also with box-packaged the same? make flexible packaging also have box-packaged can steadily standing up, to replace existing carton package, this not only can improve the displaying and the aesthetic utility of flexible packaging, and can save paper pulp, is beneficial to environmental protection.Just be based on this imagination, the inventor constantly breaks the mode of thinking of people's routine through for many years practice and exploring, innovation and creation finally a kind of new method for making to remedy the deficiency of flexible packaging.
Purpose of the present invention is exactly to disclose a kind of method that is used to make collapsible flexible packaging, and this method can be produced has that box-packaged the same bottom smoothly can steadily stand up, folding flexible packaging.
For achieving the above object, the present invention will be processed into the straight barrel type Soft Roll fitted tube of parallelogram with composite soft packaging material before this, then it was carried out back cover, and the bottom behind the back cover longitudinally is " X " shape, again described flexible packaging jacket casing is advanced supporting with it former, carry out the bottom compression molding.The compression molding of described bottom is implemented according to following step: (1) is advanced the flexible packaging jacket casing in the described former, and at the bottom Zhang Tingwei quadrangle of following described Soft Roll fitted tube of former dilating effect; (2) four angle closure part of giving prominence to the symmetry that is " X " type in the bottom respectively along the side to main positive turnover, on above-mentioned quadrangle basis, form flatly, be flat soft packaging bag through the mold pressing typing; (3) former shrinks under the elastic force effect, withdraws from from described flat soft packaging bag; (4) bottom is got final product to flattening after compression molding folds and places on one side, opening when time needs splendid attire.
Be the intensity of reinforced bottom in the described compression molding, can with glue four angle closure part and bottom surface be clinged when main positive kind of folding formation is flat along the side respectively, finalize the design through mold pressing then in described four angle closure part.
Can with box-packaged the same indeformable can in four vertical edge upper edges of described in type flat soft packaging bag to angular direction be molded into four perpendicular rib limits at splendid attire during than heavy articles for strengthening soft packaging bag in the described compression molding.
The present invention has more strong operability with respect to prior art, and advantages such as time-saving and efficiency make flexible packaging commonly used can have characteristics that rigid package has concurrently, remedies the deficiency that flexible packaging exists effectively.
Below in conjunction with accompanying drawing the present invention is made further enumeration.
Fig. 1 is the flexible packaging scheme drawing of back cover;
Fig. 2 is the scheme drawing when packing into former Zhang Tinghou turnover;
Fig. 3 is for turning down after the scheme drawing after the compression molding;
Fig. 4 is the scheme drawing after the ribbing;
Scheme drawing when Fig. 5 is stored collapsed.
The method disclosed in the present is applicable to the making of any soft packaging bag, is to be that example describes to make a soft packaging bag below.As shown in Figure 1, will be processed into the straight barrel type Soft Roll fitted tube of parallelogram with composite soft packaging material, and its side is fallen into the back back cover to invagination, the bottom behind the back cover longitudinally should be and is similar to " X " shape.And its inversion packed in the big or small with it supporting former, as shown in Figure 2, and under the former dilating effect Zhang Tingwei quadrangle, sealing part was subjected to open very and holded up naturally this moment.Turn down to main frontal along the side respectively by four angles (sealing) that illustrate the symmetry that roughly is " X " shape that to have holded up then, opened on the plane that four frames of very typing are constituted thermocompression forming at former through mould, formed flat soft packaging bag, as shown in Figure 3.
In addition, indeformable during than heavy articles for strengthening soft packaging bag at splendid attire, can when turnover shown in Figure 2, four angles (sealing) be bonded together itself and bottom surface with glue or other adhesivess respectively on the one hand,, improve the effect of surely putting to strengthen the complanation and the shape stability of bottom.On the other hand, also can be molded into four rib limits to the angular direction in four vertical edge upper edges of in type flat soft packaging bag, as shown in Figure 4, this rib limit helps strengthening the effect that erects, and makes it have more the advantage of boxlike rigid package.
At last, in type soft packaging bag is the entity with certain volume owing to it is the same with the boxlike rigid package, shelve and take up room when depositing greatly, for this reason, after moulding, utilize the plasticity of flexible packaging that its bottom is rolled over to a main positive rollover, as shown in Figure 5, finalize the design through mold pressing again, just collapsible being positioned in the warehouse, shared space in the time of can reducing it greatly and deposit during as the need splendid attire is opened it and is got final product.
