Abstract
The utility model relates to a high-obstruction transparent strippable film, and belongs to the technical field of food packaging materials. The high-obstruction transparent strippable film is characterized in that the film is formed of a PET film layer (1), an ink layer (2), a polyurethane adhesive layer (3), a silicon-coated PET film layer (4), a polyurethane adhesive layer (5) and a polypropylene inner layer (6) by tight lamination. The high-obstruction transparent strippable film has good transparency, so as to attract customers. The PET film layer and the silicon-coated PET film layer ensure moisture resistance and oxygen resistance of the strippable film, and the strippable film has good obstruction performance. The inner layer adopts homopolymer/copolymer blended polypropylene (RCPP), and has good bonding performance with a bowl. The high-obstruction transparent strippable film has good sealing performance, and can be conveniently and rapidly stripped without using handle, pull wire and pull ring.
Description
(1) technical field
The utility model relates to the transparent epiphragma of easily taking off of a kind of high-barrier.Be mainly used in the poach of tinned fruit, rice class or the packaging for foodstuff of thermophilic digestion.Belong to the packaging material for food technical field.
(2) background technology
At present, the packing of tinned food adopts the mode of glass packaging and iron box packing more.Glass canned food: with the container that glass is made, advantage is: transparent, be convenient to customer's observation and selection; Chemical property is stable, and antiacid anti-sulphur is strong, and do not have an effect and produce variable color, spoiled, rotten with food, especially suitable fruit, vegetables and the stronger food of other acidity adorned, abundant raw material, low price, and recyclable multiplexing.Shortcoming is: heavy, easily broken, and transportation inconvenience, permeability of heat is relatively poor.The can: making with tin-plate, is present most popular container.The can has perpendicular round, flat round, ladder type, square etc.Its advantage is: soft, be easy to bending, stretching, punching press, the weight ratio glass jar is light, is difficult for broken fracture, and be easy to carry, transport and take care of, good heat conductivity, the sterilizing time weak point when cold and hot steep variation, is difficult for breaking.Shortcoming is: the cost height, poor chemical stability, easily with jar in food have an effect, make the iron sheet corrosion and cause a jar interior food spoilage.In order to solve the problem that above-mentioned manner of packing exists, plastic can arises at the historic moment.It has high temperature resistant, non-corroding, in light weight, advantage such as price is low, it is jar convenient to open and display property is good.But the epiphragma of plastic can adopts aluminium foil more, and its transparency is poor, the difficult desire to buy that attracts the customer; And barrier property is bad, and content is perishable.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of high-barrier the transparent epiphragma of easily taking off, and its good barrier property, content are not perishable, and the transparency is good, can improve customer's desire to buy, and easily taking off property is good.
The purpose of this utility model is achieved in that the transparent epiphragma of easily taking off of a kind of high-barrier, it is characterized in that: it closely is composited by PET rete, ink lay, polyurethane glue-line, plating silicon PET rete, polyurethane glue-line and inner layer of polypropylene.
Be provided with priming coat between described PET rete and the ink lay.
The transparent beneficial effect of easily taking off epiphragma of a kind of high-barrier of the utility model is:
1) transparency is good, can attract customer's eyeball, improves customer's desire to buy.
2) adopt PET rete and plating silicon PET rete to guarantee its protection against the tide, antioxygen property, the epiphragma barrier property of making is good.Plating silicon PET film mainly is meant the organic matter of vacuum applying silicon oxide on polyester base material, this evaporation mode just as one deck glass-film evaporation on base film.The evaporation layer crackle can not occur in the course of processing, thereby can guarantee the low-down effect of barrier property.
3) internal layer adopts the polypropylene material (RCPP) that homopolymerization mixes with copolymerization, and is good with the bond properties of bowl body, guarantees that leak free simultaneously, is easy to open, and need not use handle, backguy, draw ring etc., convenient and swift.
4) be applicable to 121 ℃, the high-temperature sterilization of 30min, can fully guarantee the food security of content.
5) print on the PET material, the comformability of printing is good.
(4) description of drawings
The transparent section structure scheme drawing of easily taking off epiphragma embodiment 1 of a kind of high-barrier that Fig. 1 relates to for the utility model.
Fig. 2 is the section structure scheme drawing of the utility model embodiment 2.
Among the figure:
PET rete 1, ink lay 2, polyurethane glue-line 3, plating silicon PET rete 4, polyurethane glue-line 5, inner layer of polypropylene 6, priming coat 2.1.
(5) specific embodiment
Embodiment 1:
Referring to Fig. 1, the transparent epiphragma of easily taking off of a kind of high-barrier that the utility model relates to closely is composited by PET rete 1, ink lay 2, polyurethane glue-line 3, plating silicon PET rete 4, polyurethane glue-line 5 and inner layer of polypropylene 6.
The polypropylene material (RCPP) that the material of inner layer of polypropylene 6 adopts homopolymerization to mix with copolymerization.
Embodiment 2:
Referring to Fig. 2, the difference of present embodiment and embodiment 1 only is to have additional priming coat 2.1 between PET rete 1 and the ink lay 2.Priming coat 2.1 improves the adhesive fastness of PET rete 1 and ink lay 2.
Claims (2)
1. transparent epiphragma of easily taking off of high-barrier is characterized in that: it closely is composited by PET rete (1), ink lay (2), polyurethane glue-line (3), plating silicon PET rete (4), polyurethane glue-line (5) and inner layer of polypropylene (6).
2. the transparent epiphragma of easily taking off of a kind of high-barrier according to claim 1 is characterized in that being provided with priming coat (2.1) between described PET rete (1) and the ink lay (2).
