Abstract
The utility model discloses a multifunctional biaxially-oriented polyester film, which relates to a composite packaging material. The multifunctional biaxially-oriented polyester film in a four-layer structure comprises a core layer (1), two surface layers (2) and a coating layer (3), wherein the two surface layers (2) are arranged on two surfaces of the core layer (1) respectively, the two surface layers (2) and the core layer (1) are composited into an integral film structure, and the coating layer (3) is coated outside one surface layer (2). The thickness of the core layer ranges from 10 micrometers to 17 micrometers, the thickness of each surface layer ranges from 1 micrometer to 5 micrometers, and the thickness of the coating layer ranges from 1 micrometer to 5 micrometers. The multifunctional biaxially-oriented polyester film solves the problems that when an existing BOPET (biaxially-oriented polyester) film is used as a packaging material, special PET (polyester) ink needs to be used for printing, manufacturing cost is high, and an aluminum-plated layer is easy to fall off during heating when digestion materials are manufactured.
Description
Technical field
The utility model relates to a kind of multi-function double-way stretched polyester (BOPET) film compound package material.
Background technology
Biaxial stretching polyester (BOPET) film has characteristics such as intensity height, good rigidly, transparent, glossiness height; Do not have smell, tasteless, colourless, nontoxic, outstanding obdurability; Its hot strength is PC film, nylon membrane 3 times, and impact strength is 3-5 a times of BOPP film, and 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 barrier and printing; After special coat processing, BOPET can also have boiling resistance, the low temperature resistant freezing property of good hear resistance, excellence, good oil resistivity and chemical-resistant etc.The BOPET film is except nitrobenzene, chloroform, phenmethylol, and most of chemicals all can not make its dissolving.BOPET film water absorption rate is low, water-tolerant, the food that the proper packing water content is high.
The BOPET general thin needs to use the printing of PET ink special during as packaging material, and cost is higher; Aluminium coated is prone to come off when making the cooked material heating.
The utility model content
The utility model provides a kind of multi-function double-way oriented polyester film, when the utility model has solved existing BOPET film as packaging material, needs to use the printing of PET ink special, and cost of manufacture is high; And the caducous problem of aluminium coated when making the cooked material heating.
For addressing the above problem, the utility model adopts following technical scheme: constitute by four-layer structure, wherein one deck be sandwich layer 1, two-layer be top layer 2, one deck is an overlay 3; 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 compound membrane structure that becomes one scribble overlay 3 in the outside on one deck top layer 2.
Said core layer thickness is the 10-17 micron; Said each skin depth is the 1-5 micron; Overlay thickness is the 1-5 micron.
The utility model advantage: 1. on the structure: this product is 4 layers of structure, adopts online coated technique to increase overlay on one of film top layer, and it is functional to have expanded film; 2. on the function: 1. need not to use the printing of PET ink special, be suitable for universal printing ink, significantly save production cost; 2. the compound fastness of aluminium lamination satisfies the requirement of making cooked material, and aluminium coated is firm during heating, difficult drop-off.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: sandwich layer 1, top layer 2, overlay 3.
The specific embodiment
As shown in Figure 1, the multi-function double-way oriented polyester film is made up of four-layer structure, wherein one deck be sandwich layer 1, two-layer be top layer 2, one deck is an overlay 3; 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 compound membrane structure that becomes one scribble overlay 3 in the outside on one deck top layer 2.
Said core layer thickness is 10 microns; Said each skin depth is 2 microns; Overlay thickness is 2 microns.
The said goods is to form above-mentioned top layer, sandwich layer through co-extrusion, stretching process, forms overlay through online coating.The sandwich layer main component is the PET resin, and the top layer is the PET masterbatch, and overlay is a high-temperature resistant water soluble polyurethane glue.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, online coating, cross directional stretch system film; Film becomes parent roll at traction unit through corona treatment, cuts into finished film at last.
This product has increased online working procedure of coating in film-forming process, improve and expanded the BOPET film performance.Compare with common BOPET film, advantage is mainly reflected in following aspect: common printed printing ink conformability is good, need not to use the printing of PET ink special, is suitable for common ink, significantly saves production cost; Be applicable to the machining cooking based packaging material: the compound fastness of aluminium lamination satisfies makes the cooked material requirement, and aluminium coated is firm during heating, difficult drop-off; Can cut down the consumption of energy and environmental protection in the production.
PET described in the above-mentioned material for the PETG chemical formula is-[OCH2-CH20COC6H4CO]-English name: polyester terephthalate; Be called for short PET; Be high polymer, by ethylene glycol terephthalate generation dehydration condensation.Ethylene glycol terephthalate is by terephthalic acid (TPA) and ethylene glycol generation esterification gained.
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 give exhaustive 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-function double-way oriented polyester film is characterized in that, constitute by four-layer structure, wherein one deck be sandwich layer (1), two-layer be top layer (2), one deck is overlay (3); Two-layer top layer (2) is arranged at sandwich layer (1) two sides respectively, two-layer top layer (2) and the compound membrane structure that becomes one of one deck sandwich layer (1), and the outside of one deck top layer (2) scribbles overlay (3) therein.
2. multi-function double-way oriented polyester film according to claim 1 is characterized in that said core layer thickness is the 10-17 micron; Said each skin depth is the 1-5 micron; Overlay thickness is the 1-5 micron.
