Abstract
The invention relates to a food packing material which is a laminated packing material comprising a paper core layer, a blocking layer and a thermoplastic resin layer, wherein the blocking layer comprises polyvinyl alcohol and tiny layered silicate, and the thermoplastic resin layer comprises a resin composition containing a plant derived plastic material and having melt extrusion capacity. Through the technical scheme, the biodegradable laminated packing material with excellent oxygen blocking performance is achieved.
Description
Technical field
The invention belongs to packaging field, refer to a kind of food laminate wrapping material.
Background technology
Drinks as the wrapping paper container of milk, fruit juice and mineral water be to be provided by the paper web shape laminate wrapping material that there is broken line and be printed with outside design.Described paper web shape laminate wrapping material forms tubulose with Production and Packaging paper container by longitudinal sealing in the vertical.Liquid food is filled in tubular packaging material.By described tubular packaging material transverse sealing cutting in the horizontal.Along the folding described packaging material of broken line, and form net shape.
Laminate wrapping material has thermoplastic innermost layer conventionally as polyvinyl resin layer, the aluminium foil layer of barrier layer, refill layer and polyvinyl resin outermost layer.
Summary of the invention
The laminate wrapping material that the object of this invention is to provide a kind of biological degradability of oxygen barrier properties excellence.
The present invention is achieved by the following technical solutions:
Packaging material, comprise the laminate wrapping material of refill layer, barrier layer and thermoplastic resin; Described barrier layer comprises polyvinyl alcohol and small phyllosilicate; Described thermoplastic resin comprises the plastic material that contains plant derivation and has the resin combination that melt extrudes ability;
The plastic material of described plant derivation comprises the plastic material of the high MFR plant derivation with the averag density of 0.910-0.925 and the melt flow rate (MFR) of 5-20 and has the plastic material of the high SR plant derivation of the averag density of 0.910-0.925 and the swelling ratio of 1.55-1.75; The ratio of the amount of substance of the plastic material of the plastic material of described high MFR plant derivation and high SR plant derivation is 3:2;
In described barrier layer, also include the oxide of zinc; The particle diameter of the oxide of described zinc is nanoscale.
The amount of layered silicate is the 0.5-0.8% of polymer weight.
The amount of the oxide of described zinc is the 0.05-0.1% of polymer weight.
