Abstract
The utility model discloses a composite film for packaging food, which comprises a core layer. The upper side of the core layer is coated with a polylactic acid layer and the lower side of the core layer is coated with a polyvinyl alcohol layer. The core layer is composed of two paper layers and a polyvinyl alcohol layer. The polyvinyl alcohol layer is positioned between the two paper layers. The composite film for packaging food of the utility model has easy natural degradation and good folding performance, water resistance, air separating performance and hot sealing performance. The utility model is very suitable for being used for manufacturing liquid food packaging containers.
Description
The utility model belongs to the packaging for foodstuff field, relates to 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, include sandwich layer, and be coated with polylactic acid layers at the sandwich layer upside, be coated with polyvinyl alcohol layer at the sandwich layer downside.
Advantage of the present utility model: the one, described used for packing foods complex film can be folded into corresponding package shape according to the packing needs of liquid food; The 2nd, described used for packing foods complex film has adopted poly(lactic acid) and polyvinyl alcohol as skin, and therefore, it is degraded more under field conditions (factors); The 3rd, described used for packing foods complex film 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, polylactic acid layers (1) and polyvinyl alcohol layer (5), and polylactic acid layers (1) is coated the sandwich layer upside, and polyvinyl alcohol layer (5) is coated the sandwich layer downside.Above-mentioned sandwich layer is made up of two layers of ply of paper (2) (4) and layer of polyethylene alcohol layer (3), and polyvinyl alcohol layer (3) is positioned between two layers of ply of paper (2) (4).The used material of ply of paper (2) (4) mainly is a vegetable fibre.
The used material of the ply of paper of above-mentioned used for packing foods complex film (2) (4) can be based on syntheticfibres.
Used for packing foods complex film described in the utility model must 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, or the liquid food packing container of other shape.
Claims (3)
