Abstract

The present invention discloses a composite material for package of food and a production method thereof. The composite material for package of food comprises a sandwich layer and an outer layer, the outer layer is coated on the sandwich layer, the outer layer is a polylactic acid layer or a polylactic acid copolymer layer, and a polylactic acid or a polylactic acid copolymer is coated on the sandwich layer by an extrusion method or a coating method. The present invention is suitable for manufacturing a liquid food packaging bag.

Description

Composite material for package of food
Technical field
The invention belongs to the packaging for foodstuff field, relate to a kind of composite material for package of food.
Background technology
The disclosed Chinese patent 1055506A in 1991 (application number is 90105802.5) has introduced a kind of three-layer plastic compound film.But with the difficult liquid food packing container that is manufactured with certain collapsed shape of this laminated film, and this laminated film is difficult for degraded under field conditions (factors), is unfavorable for environmental protection.
Summary of the invention
The objective of the invention is to develop a kind of composite material for package of food at above-mentioned deficiency.
Embodiment of the present invention are: a kind of composite material for package of food, comprise sandwich layer and skin, and on sandwich layer, be coated with skin, this skin is polylactic acid layers or copolymer of poly lactic acid layer; Sandwich layer is a double-decker, and this double-decker can be made up of ply of paper and plastic layer, also can be formed or be made up of aluminium foil layer and plastic layer by ply of paper and aluminium foil layer.
Advantage of the present invention: described composite material for package of food can be folded into corresponding package shape according to the packing needs of liquid food; The skin of this composite material for package of food is polylactic acid layers or copolymer of poly lactic acid layer, so degraded more under field conditions (factors).
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in the figure, the present invention includes sandwich layer 1 and two layers of skin 2, skin is polylactic acid layers or copolymer of poly lactic acid layer, and these two layers of skins 2 are applied respectively in the upside and the downside of sandwich layer 1.Sandwich layer 1 is a double-decker, and this double-decker is made up of ply of paper and plastic layer.
The used material of ply of paper mainly is string or synthetic fibers, and the used material of plastic layer mainly is a TPO.
The double-decker of sandwich layer 1 also can be made up of ply of paper and aluminium foil layer.
The double-decker of sandwich layer 1 also can be made up of aluminium foil layer and plastic layer.
The skin 2 of above-mentioned composite material for package of food can be one deck, and this one deck outer 2 is applied in a side of sandwich layer 1.
The production method of above-mentioned composite material for package of food is an extrusion molding, and the production technology of extrusion molding is with extruder PLA or copolymer of poly lactic acid to be expressed on the sandwich layer 1, and PLA or copolymer of poly lactic acid are applied on the sandwich layer 1 with the form of thin layer.
The production method of above-mentioned composite material for package of food also can be coating process, and the production technology of coating process is to use coating device, and PLA or copolymer of poly lactic acid are applied on the sandwich layer 1 with the form of thin layer.
