Abstract
The object of the present invention is to provide a kind of improved-type PE heat-sealing films, which is made by the raw material of following percentage by weight：20~24% LLDPE7042；24~27% LLDPE2426；11~14%LLDPE800A；7%MDPE metallocenes；25~27%EVA.Heat-sealing film provided by the invention is improved by being formulated, and raw material blending, changes molecular structure, is that individual layer is spiral, realizes that single screw rod is produced, it can be achieved that low temperature sealing, improves production efficiency；Increase film strength, while preventing bale broken, reduce cost.LLDPE7042 is major ingredient, reduces cost, and LLDPE2426 mobility reduces, is combined together, changes the problem of film is uneven；LLDPE800A make it that sealing temperature reduces, and MDPE metallocenes are used so that playing envelope temperature reduces.Viscosity rise, intensity enhancing.
Description
Technical field
The invention belongs to PE film applications, and in particular to a kind of improved-type PE heat-sealing films.
Background technology
PE films, that is, polyethylene film, makings are also known as non-stretched poly- by the flat polyethylene film squeezed into blow moulding and produced
Vinyl film.With polypropylene film, polyester film compared with polyvinyl chloride film, not only cost is relatively low for PE films, but also has
Good pliability, heat sealability and vertically and horizontally performance；And PE films can also be aluminized after sided corona treatment, printed,
Or it is compound with other materials, performance more preferably film is obtained, therefore PE films are widely used as food, daily necessities and electronics production
The packaging material of product etc., is that current application is used as extensive plastic package material.In addition, PE films are with excellent water
Steam and gas barrier property, be especially suitable for toilet article packaging film.Existing PE films are multilayer, such as film-Buddhist nun
Dragon-film；Complex manufacturing technology.
The content of the invention
The object of the present invention is to provide a kind of improved-type PE heat-sealing films, the PE heat-sealing films by following percentage by weight original
Material is made：20~24% LLDPE7042；24~27% LLDPE2426；11~14%LLDPE800A；7%MDPE metallocenes；
25~27%EVA.
Compared with prior art, the invention has the advantages that：
Heat-sealing film provided by the invention is improved by formula, and raw material blending, changes molecular structure, is that individual layer is spiral, is realized
Single screw rod produces, it can be achieved that low temperature sealing, improves production efficiency；Increase film strength, while preventing bale broken, reduce cost.
LLDPE7042 is major ingredient, reduces cost, and LLDPE2426 mobility is reduced, is combined together, and changes film injustice
The problem of；LLDPE800A make it that sealing temperature reduces, and MDPE metallocenes are used so that playing envelope temperature reduces.Viscosity rise, by force
Degree enhancing.
