Abstract
The utility model discloses a light-elimination type multi-functional polyamide preservation film, relating to a composite packaging material. The film is composed of three layers of structures, i.e. one core layer (1) and two surface layers (2); the two surface layers (2) are arranged at two surfaces of the core layer (1) respectively; and the two surface layers (2) and the one core layer (1) are laminated into an integral film structure, wherein the core layer is a preservation layer with high-barrier materials, and one of the two surface layers (2) is a light-elimination layer with light-elimination materials. According to the film, the technical problems that a conventional PA (Polyamide) preservation film is high in cost and is generally manufactured by compositing multiple layers of films or by casting a plurality kinds of materials are solved.
Description
Technical field
The utility model relates to a kind of compound package material.
Background technology
The general material amount of existing preservative film PA, the preservative film cost of PA is higher; And be mostly the compound or multiple material curtain coating making of plural layers, there are a lot of technological deficiencies in manufacturing process, causes poor product quality.
The utility model content
The utility model provides a kind of extinction type multi-functional polyamide antistaling film, and it is higher that the utility model has solved existing P A preservative film cost; And be mostly the technical problem that the compound or multiple material curtain coating of plural layers is made existence.
For addressing the above problem, the utility model adopts following technical scheme: the multi-functional polyamide antistaling film of extinction type, constitute by three-decker, wherein one deck be sandwich layer (1), two-layer be top layer (2); Two-layer top layer (2) is arranged at sandwich layer (1) two sides respectively, and two-layer top layer (2) and one deck sandwich layer (1) are suppressed into the membrane structure of one, and its center core layer (1) is for containing the fresh-keeping layer of high barrier material, and the one deck in top layer (2) is the delustring layer that contains extinction material.
Said core layer thickness is the 10-20 micron; Said each skin depth is the 1-3 micron.
The utility model advantage: 1. on the structure: this product is a three-decker, adopts stretch processes, uses PP/PE/PA blend composition and extinction material, and it is functional to have expanded film; 2. on the function: 1. need not secondary operations, can use as matt film and preservative film separately, significantly save production cost; 2. high obstructing performance has guaranteed the fresh-keeping effect of packing material, and has good delustring outward appearance, promotes the sensory effects of packing.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the multi-functional polyamide antistaling film of extinction type is made up of three-decker, wherein one deck be sandwich layer (1), two-layer be top layer (2); Two-layer top layer (2) is arranged at sandwich layer (1) two sides respectively; Two-layer top layer (2) and one deck sandwich layer (1) are suppressed into the membrane structure of one; Its center core layer (1) is for containing the fresh-keeping layer of high barrier material; One deck in the top layer (2) is the delustring layer that contains extinction material, and an other top layer can be common PP thin layer.
Said core layer thickness is the 10-20 micron; Said each skin depth is the 1-3 micron.
The said goods is through co-extrusion, stretching process and form above-mentioned top layer, sandwich layer.The sandwich layer main component is PP or PP/PE/PA blend composition and little additive, and the top layer mainly is extinction material and PP masterbatch or PP.Process is: with the raw material auxiliary material send into feed bin, high-pressure delivery to extruder plastifies into melt; Melt filters through pipeline transmission, filter; Be assigned to die head through runner, become the casting sheet through cold cydariform, thereafter through longitudinal stretching, cross directional stretch system film; Film becomes parent roll at traction unit through corona treatment, cuts into finished film at last.
This product directly uses the PP/PE/PA blend composition in film-forming process; Compare during with general thin or PA film as the preservative film purposes; Advantage is mainly reflected in following aspect: need not compound or following process such as curtain coating; High obstructing performance has guaranteed the fresh-keeping effect of packing material, and has good delustring outward appearance, promotes the sensory effects of packing; Can cut down the consumption of energy and environmental protection in the production.
PP described in the above-mentioned material is a polypropylene: chemical formula for-CH2--CH (CH3)-]-n, be propylene resulting product of polymerization reaction take place under catalyst action, English name: Polypropylene (being called for short PP); PE is HDPE, just low-pressure high-density polyethylene: chemical formula is-[CH2-CH2-]-n, is the polyethylene of low-pressure polymerization (ziegler process) gained, English name: Polyethylene (being called for short PE); PA is polyamide (nylon): chemical formula :-[NH-(CH2) 5-CO] n-is made English name through polycondensation reaction by adipic acid and hexamethylene diamine: Polyamide (being called for short PA).
The multi-functional polyamide antistaling film of extinction type is that biaxial tension generates, and has the film of delustring outward appearance and good fresh-keeping function, and its main component is PP/PE/PA; Have characteristics such as intensity height, good rigidly, barrier property be good; Do not have smell, tasteless, nontoxic, outstanding obdurability; Excellent abrasion resistance, folding resistance, anti-pin hole property and tear resistance etc. are arranged; Heat-shrinkable is minimum; Has good antistatic behaviour, the adhesive force of heat sealability, barrier and printing; Simultaneously, the multi-functional polyamide antistaling film of extinction type also has good hear resistance, low temperature resistant freezing property, good oil resistivity and chemical-resistant etc., except nitrobenzene, chloroform, phenmethylol, most of chemicals all can not make its dissolving; In addition, the multi-functional polyamide antistaling film of extinction type water absorption rate is low, water-tolerant, printing performance is good; Has the excellent apparent effect of delustring; The food that the proper packing water content is high especially under moist or freezing situation, has still kept excellent oxygen barrier property; So, be a excellent fresh-keeping packaging material to the chilled beverage of smell sensitivity and the fresh-keeping aspect of food.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't enumerate one by one to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
Claims (2)
1. the multi-functional polyamide antistaling film of extinction type is characterized in that, constitute by three-decker, wherein one deck be sandwich layer (1), two-layer be top layer (2); Two-layer top layer (2) is arranged at sandwich layer (1) two sides respectively, and two-layer top layer (2) and one deck sandwich layer (1) are suppressed into the membrane structure of one, and its center core layer (1) is for containing the fresh-keeping layer of high barrier material, and the one deck in top layer (2) is the delustring layer that contains extinction material.
