Abstract
The utility model relates to sheet material used for food packing, and belongs to the commodity packing sectional material. The utility model discloses the technical proposal that a basis material layer is formed by mixing and pressing talcum powder, polypropylene and polyethylene glycol, or talcum powder, polystyrene and polyethylene glycol, polypropylene or polystyrene material co-existing layers are arranged on the both side surfaces of the basis material layer, and a sealing layer is arranged on the outer surface of a co-existing layer. The utility model has the advantages that the intensity is good, the heat sealing performance is good, the obstructing performance is higher, the utility model is high and low temperature resistant, and oil proof, when being set on fire, the carbon dioxide discharging amount is small, in addition, the production cost is low.
Description
Technical field
The utility model relates to the section bar of article packing section bar, particularly used for packing foods.
Background technology
French talc is a kind of natural materials, has degradable and advantages of being cheap, and its oil resistant, high-low temperature resistant, obstruct aqueous vapor intercept performance such as oxygen and surpass materials such as polypropylene, polystyrene, replaces wrapping materials such as polypropylene, polystyrene just gradually.But the french talc material can not direct contact food, and the french talc material can not directly connect co-extrusion altogether with plastics, and its Heat forming is difficulty more.
Summary of the invention
The purpose of this utility model provides a kind of used for packing foods sheet material, and the substrate layer of this sheet material mainly is made up of the french talc material, and its intensity is good, and heat sealability is good, and higher barrier is arranged, but high-and low-temperature resistance, oil resistant, and low cost of manufacture.
Technical solution of the present utility model is that the two sides of the substrate layer that mixes by french talc, polypropylene and carbowax or by french talc, polystyrene and carbowax are provided with polypropylene or polystyrene material conjugate layer, is provided with barrier layer on the outside face of conjugate layer.
The thickness of substrate layer of the present utility model can be 0.1mm～2.0mm.
The thickness of conjugate layer of the present utility model can be 0.03mm～1.0mm.
Can be coated with polyvinylidene chloride and acrylic copolymer barrier layer on the outside face of the conjugate layer of above-described substrate layer.
The coating weight of above-described copolymer barrier layer can be 3g/m
2～80g/m
2
Can be provided with color printing polythene material barrier layer on the outside face of the conjugate layer of substrate layer of the present utility model.
The thickness of above-described color printing polythene material barrier layer can be 0.01mm～0.80mm.
Can be provided with polypropylene, EVOH, composite polyethylene material barrier layer on the outside face of the conjugate layer of substrate layer of the present utility model.
The thickness of above-described polypropylene, EVOH, composite polyethylene material barrier layer can be 0.01mm～1.2mm.
The utility model has the advantages that intensity is good, heat sealability is good, and higher barrier is arranged, but high-and low-temperature resistance, oil resistant, the CO2 emissions in the time of can reducing waste material and burn, and low cost of manufacture.
