Abstract

The invention discloses a high-temperature-resistant and high-barrier multilayer compound film for packaging bags. The high-temperature-resistant and high-barrier multilayer compound film comprises polyester film layers, polyester aluminized film layers and polyethylene film layers which are sequentially compounded with one another. The polyethylene film layers comprise, by weight, 20-30 parts of low-density polyethylene, 15-25 parts of polypropylene random copolymers and 45-62 parts of linear low-density polyethylene or metallocene polyethylene. The high-temperature-resistant and high-barrier multilayer compound film for the packaging bags has the advantages that the aluminized film layers are high in barrier, various raw materials are reasonably proportioned, accordingly, synergistic effects of the various raw materials can be sufficiently realized, the polyethylene film layers are excellent in high-temperature resistance, products in the packaging bags are stable in property, and the shelf lives of packaged contents can be prolonged; solvent-free compounding processes are implemented for the adjacent film layers, the gluing amount is 1.4-1.6 g/m<2> under the control, accordingly, the hygienic properties of the products can be improved while the compound bonding strength is guaranteed, residual solvents can be prevented, and contamination on the packaged contents can be reduced.

Description

High temperature resistant high-barrier multi-layer compound package bag film
Technical field
The invention belongs to packaging bag manufacturing technology field, be specifically related to a kind of high temperature resistant high-barrier multilamellar multiple Close bag membrane.
Background technology
Packaging bag refers to the sack for packing various articles for use, makes goods convenient in producing the process of circulation Transport, easily stores.It is widely used in daily life and commercial production.Prior art is used for manufacture The most generally there is high temperature resistant and that barrier is poor problem in bag membrane, causes bag membrane in some field
Summary of the invention
To this, it is desirable to provide a kind of barrier and the good combined package bag film of resistance to elevated temperatures.
The technical scheme realizing the object of the invention is:
A kind of high temperature resistant high-barrier multi-layer compound package bag film, by polyester film, polyester aluminium plating membrane and Polyethylene film layer is sequentially compounding, and described polyethylene film layer is made up of the proportioning raw materials of following weight portion: Low Density Polyethylene 20-30 part, polypropylene random copolymer 15-25 part, linear low density polyethylene or Person's metallocene PE 45-62 part；
The melt index of described Low Density Polyethylene is 1.0-2.0g/10min, described polypropylene random copolymerization The melt index of thing is 1.0-3.0g/10min, and the melt index of described linear low density polyethylene is 1.0-2.0g/10min, or the melt index of described metallocene PE is 0.5-2.5g/10min.
In technique scheme, the thickness of described polyethylene film layer accounts for more than the 60% of bag membrane thickness, And the thickness of described polyethylene film layer is not less than 20um.
In technique scheme, described polyethylene film layer outer layer has corona processing layer, and its corona value exists Between 38-42.
The present invention has a positive effect: in (1) bag membrane of the present invention due to have aluminium plating membrane because of And there is higher barrier, and simultaneously because polyethylene film layer has polyethylene film layer, described poly-second Alkene film layer is made up of the proportioning raw materials of following weight portion: Low Density Polyethylene 20-30 part, polypropylene without Rule copolymer 1 5-25 part, linear low density polyethylene or metallocene PE 45-62 part, and institute The melt index stating Low Density Polyethylene is 1.0-2.0g/10min, melting of described polypropylene random copolymer Melting index is 1.0-3.0g/10min, and the melt index of described linear low density polyethylene is 1.0-2.0g/10min, or when the melt index of described metallocene PE is 0.5-2.5g/10min, logical Cross the above-mentioned rational proportioning of each raw material, give full play to the synergism between each raw material, so that resistance to Polyethylene film layer has good resistance to elevated temperatures.
