Abstract
The utility model discloses a composite film for food package, which comprises a core layer and an outer layer. The core layer is coated with the outer layer. The outer layer is a copolymer layer of poly hydroxy butyl ester and poly hydroxy pentylamine. The utility model has easy natural degradation and good folding performance, water resistance, gas separating performance and hot sealing performance. The utility model is very suitable for being used for manufacturing liquid food packing containers.
Description
The utility model belongs to the packaging for foodstuff field, specifically a kind of used for packing foods complex film.
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.
The purpose of this utility model is at above-mentioned deficiency, develops a kind of used for packing foods complex film.
Embodiment of the present utility model is: a kind of used for packing foods complex film, comprise sandwich layer and skin, and on sandwich layer, be coated with skin, this skin is poly-hydroxyl fourth fat and poly-hydroxyl penta resin copolymer layer.
Advantage of the present utility model: the one, it can be folded into corresponding package shape according to the packing needs of liquid food; The 2nd, because it has adopted poly-hydroxyl fourth fat and poly-hydroxyl penta resin copolymer layer as skin, therefore, degraded more under field conditions (factors); The 3rd, it has waterproof, trapping and heat sealability preferably.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of square liquid food packing box.
Fig. 3 is the structural representation of roof shape liquid food packing box.
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises sandwich layer 1 and two layers of skin 2, and outer 2 are poly-hydroxyl fourth fat and poly-hydroxyl penta resin copolymer 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 ply of paper, and the used material of this ply of paper mainly is vegetable fibre or syntheticfibres.
The skin 2 of above-mentioned used for packing foods complex film can have only one deck, and this one deck outer 2 is applied in a side of sandwich layer 1.
The sandwich layer 1 of above-mentioned used for packing foods complex film can be plastic layer, and the used material of this plastic layer is mainly polyolefins.
The sandwich layer 1 of above-mentioned used for packing foods complex film can be aluminium foil layer.
The sandwich layer 1 of above-mentioned used for packing foods complex film can be made up of ply of paper and plastic layer, and the used material of ply of paper mainly is vegetable fibre or syntheticfibres, and the used material of plastic layer mainly is a polyolefins.
The sandwich layer 1 of above-mentioned used for packing foods complex film can be made up of ply of paper and aluminium foil layer, and the used material of ply of paper mainly is vegetable fibre or syntheticfibres.
The sandwich layer 1 of above-mentioned used for packing foods complex film can be made up of aluminium foil layer and plastic layer, and the used material of plastic layer mainly is a polyolefins.
Contain 95% poly-hydroxyl fourth fat and 5% poly-hydroxyl penta fat in above-mentioned described poly-hydroxyl fourth fat and the poly-hydroxyl penta resin copolymer layer, or contain 60% poly-hydroxyl fourth fat and 40% poly-hydroxyl penta fat.
Above-mentioned described used for packing foods complex film can be made square liquid food packing box as shown in Figure 2, also can make roof shape liquid food packing box as shown in Figure 3.
