Description
Technical field
The present invention relates to printing packaging technical field, specially a kind of boiling level is cast compound CPP films.
Background technology
Casting films are that the cast film of a kind of tensionless winkler foundation for being quenched production, non-directional is salivated by melt, there is individual layer salivation
With multi-layer co-extruded salivation two ways.Compared with blown film, it is characterized in that speed of production is fast, yield is high, the transparency of film, gloss
Property, thickness evenness etc. are all extremely outstanding.Simultaneously as being cast film subsequent handling, such as print, be compound all extremely square
Just, thus it is widely used in the packaging of food, medical supplies, textile, fresh flower, commodity.China's salivation film production starting
Later (the 1980s), basis is more weak, but development speed is very fast.Grow by continuous development in the past 20 years, I
State salivates film at present has turned into the rising industry with suitable production capacity and the level of production in packaging industry.
Retort packaging is one of faster packaging classification of development over the past two years.Digestion resistant food pack is (following
Referred to as resistance to retort pouch), be commonly called as foods packed in carton containers, its most outstanding feature be place for a long time at normal temperatures without occur it is putrid and deteriorated；
Using also easily, can cold food again can heat boil.Current resistance to retort pouch is mainly used in packing tinned food, prepared food etc., Japan,
West Europe is also used for packaged beverage, fruit juice, mashed potatoes, cereal foods etc., and boiling level refers to that dry type can be passed through with PET, NY, aluminium foil etc.
After compound, the compound of digestion resistant sterilization is made and uses base film.Non- boiling level refers to that retort pouch internal layer base material can not be done, only
The film routinely packed can be used for.
Relative to common CP P films, thermophilic digestion CPP films have special performance requirement：High temperature resistant, high pressure, have outstanding
Heat seal strength, combined strength bination.Its physical property will not also decline, not rupture, be air tight after boiling, and food undergoes no deterioration in bag
It is spoiled.Low-temperature-resistant, not embrittlement in refrigeration are required in transport and sale.The use of this new packaging material, not only greatly
The big shelf-life for extending food, the fresh and nutrition of food is maintained to greatest extent, and reduce to a great extent
Vacuumize, high pressure, pressure oscillation when bale broken phenomenon, so as to largely reducing cost, popularized high-grade convenient food
The packaging of product.Everything all proposes higher requirement to the raw material acrylic resin for manufacturing thermophilic digestion CPP films, not only
Ensure that it possesses excellent film forming processing characteristics, also to make obtained film that there is good mechanical performance and optical property.Often
The shortcomings of definition is not high, erosion-resisting characteristics is poor, easy to crack, non-refractory be present in the thermophilic digestion CPP films seen.
The content of the invention
For the above-mentioned problems in the prior art, a kind of stability proposed by the present invention is good, definition is high, impact resilience
Can the compound CPP films of good, not easy to crack, resistant to elevated temperatures boiling level curtain coating.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of boiling level is cast compound CPP films, includes successively：Hot sealing layer, sandwich layer and corona layer, the sandwich layer are set
Put between hot sealing layer and corona layer；By weight percentage, the hot sealing layer accounts for 14%~20%, and the sandwich layer accounts for 55%~
65%, the corona layer accounts for 20%~25%；
By weight percentage, the hot sealing layer by ternary polymerized polypropylene 88%~95%, surfactant 3%~
8%th, slipping agent 2%~5% forms, and the sandwich layer includes HOPP 90%~96%, toughener 4%~10%, described
Corona layer includes HOPP 50%~65%, ternary polymerized polypropylene 20%~35%, metallocene POE5%~10%, anti-
Electrostatic coatings 5%~12%.
Preferably, by weight percentage, the hot sealing layer accounts for 17%, and the sandwich layer accounts for 60%, and the corona layer accounts for
23%；By weight percentage, the hot sealing layer is by ternary polymerized polypropylene 90%, surfactant 6.5%, slipping agent
3.5% composition, the sandwich layer include HOPP 93%, toughener 7%, the corona layer include HOPP 58%,
Ternary polymerized polypropylene 27%, metallocene POE 8%, antistatic coating 7%.
Beneficial effects of the present invention：
A kind of boiling level of the present invention is cast compound CPP films, with ternary polymerized polypropylene, surfactant, slipping agent
Hot sealing layer is made, sandwich layer is made with HOPP, toughener, with HOPP, ternary polymerized polypropylene, metallocene, anti-
Corona layer is made in electrostatic coatings, and boiling level that is compound and going out is cast compound CPP films, and product quality is light, and stability is good, definition
Height, erosion-resisting characteristics is good, wear-resistant, not easy to crack, has excellent high temperature resistance performance.
