Description
Technical field
The present invention relates to packing technique field, and in particular to a kind of transparent sealed membrane for Easy tearing lid, preparation method and
Transparent Easy tearing lid.
Background technology
Drawing lid and lid for the pop can of packaging for foodstuff are generally that metal is made, and draw fix tightly between lid and lid
Gu so that draw lid to open difficult.In addition, if after being pulled open from La Gai, lid mouth is sharp due to metal edges after can opening, it is also possible to can draw
Broken user's skin.Develop later and pull open the Easy tearing lid product easy open cover to be replaced that part is made up of aluminium foil.Aluminium foil Easy tearing lid
It is full metal sealing with easy open cover, does not possess perspectivity, limited to understanding of the consumer to product in tank, consumption is reduced sometimes
The desire to buy of person and the trust to product.And aluminium foil is replaced using common packaging for foodstuff hyaline membrane, there is difficult processing, anti-corrosion again
Property it is poor, seal it is unstable the problems such as.
The content of the invention
The present invention is regarding to the issue above, there is provided a kind of transparent sealed membrane for Easy tearing lid, preparation method and transparent easily tear
Lid.
The technical solution used in the present invention is as follows：A kind of transparent sealed membrane for Easy tearing lid, including be brought into close contact
Pet film layer and hot sealing layer.

Word and/or pattern can be printed with the pet film layer.
Transparent sealed membrane in preferred scheme one, its preparation process is as follows：The pet film
Layer and hot sealing layer are combined by dry type or solvent-free compound mode adds binder to be brought into close contact, followed by aging.Preferably, institute
Pet film layer is stated to be combined by dry type for two-layer pet film or without molten
The compound mode of agent adds binder to be brought into close contact to be formed.The combination of two-layer pet film can strengthen envelope
Mouth film strength, deflection.The hot sealing layer formed by modified poly ethylene film or cast polypropylene film, its thickness is 20 μm -100
μm.Modified poly ethylene film and polypropylene film have excellent heat sealability.With decorative cover heat-sealing, function admirable, with easily taking off
The property opened.
Transparent sealed membrane in preferred scheme two, its preparation process is as follows：By glue spreader in poly terephthalic acid second two
Alcohol ester thin-film surface adds heat-seal adhesive to form hot sealing layer, it is preferable that the pet film layer is two
Layer pet film is combined by dry type or solvent-free compound mode adds binder to be brought into close contact shape
Into followed by aging.Heat-seal adhesive has excellent heat sealability.With decorative cover heat-sealing, function admirable, with the easy property opened.
Gluing process can be completed by glue spreader, and the control parameter of gluing process is as follows：
Application rate：50-100 ms/min；

A kind of method being combined with each other, it is compound also known as response type.Solvent-free compound control parameter is as follows：
Speed：Less than or equal to 400 ms/min；
Metering roll temperature is 35-50 DEG C, and gluing roll temperature is 40-55 DEG C；
Hot drum binding temperature：40-60℃；
Spread：1.0-4.0g/m2/ layer.
Preferably, the thickness of binder is 1-5 μm.
Preferably, the thickness per strata ethylene glycol terephthalate is 6 μm -150 μm.That is individual layer poly terephthalic acid second
The pet film thickness degree that terephthalate films are formed is 6 μm -150 μm, two-layer poly terephthalic acid second
The pet film thickness degree that terephthalate films are formed is 13-305 μm.
Preferably, the condition of curing is as follows：At 35-60 DEG C, the curing time is more than or equal to 48 h.
A kind of transparent Easy tearing lid, including lid, sealed membrane, the lid are provided with and take thing hole, and the ParafilmTM takes
Thing hole, the sealed membrane is above-mentioned transparent sealed membrane.
Beneficial effects of the present invention are as follows：Hyaline membrane Easy tearing lid has had both the advantage of Easy tearing lid and plastic, transparent film.It is transparent
Film Easy tearing lid is made bezel ring, by aluminium or iron material, is fitted under conditions of HTHP with transparent polymer composite membrane and formed.Open
Qi Shi, need to only tear hyaline membrane.Than traditional easy open cover and the canned packaging of sled lid combination cover form, hyaline membrane is easy
Tear to cover does not have tiny coating bits and metal fillings to fall into the secondary pollution caused in tank to food when uncapping, the metal after treatment
Decorative cover does not have sharp edge, has prevented the potential danger of scratching fingers, so that there is provided a kind of packaging of new hommization
Selection.The use of hyaline membrane, makes consumer can directly be seen that the food situation in packaging, it is to avoid corrupt expired food is purchased
Buy, enhance the sense of security of consumer.Meanwhile, the visualization of delicacy is also by the desire to buy for stimulating consumer.In addition, transparent
Can be presented on various graph text informations in packaging using technologies such as intaglio printings by film, make product more attractive in appearance.In sum,
It can be seen that hyaline membrane Easy tearing lid have it is convenient open, safe and reliable, texture is slim and graceful, good appearance and it is rich and changeful the advantages of.Can be wide
The general drysaltery packaging for being applied to the leisure food such as nut, candy, can also be applied to the sterilized and hot filling such as fruit, fish, soup
Fill the packaging of product.
