Abstract
The invention relates to a material for packing the multiple layer compound table salt, which is mainly used to produce the packing bag of table salt. The invention is characterized in that: it comprises the surface layer of white brown paper (3), the intermediate layer of polyethylene adhesive agent layer (4) and the inner layer of polyethylene layer (5). Since the invention utilizes the polyethylene adhesive agent to combine the surface layer of white brown paper with the inner layer of polyethylene, the material do not contain the chemical solvent residue as benzene, alcohol, and ketone which are harmful to the human body, to meet the demand of food sanitation.
Description
Technical field:
The present invention relates to a kind of packaging material for food, especially relate to a kind of multilayer composite packaging material for edible salt.Be mainly used in and make the edible salt packaging bag.Belong to field of packaging material.
Background technology:
Before the present invention makes, at present mainly contain two kinds at the used a kind of flexible packing material of edible salt packaging industry: a kind of system is with the polyester film and polyethylene is compound makes, another kind of constitute by three layers of polypropylene, blank sheet of paper and polyethylenes are compound, the shortcoming of these two kinds of packings is: all adopt glue to be bonded together between two neighbours are two-layer, and all contain harmful chemical industry dissolvent residuals such as benzene, fat, ketone in this glue, thereby this salt packing do not meet the requirement of food hygiene.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of multilayer composite packaging material for edible salt that does not contain the chemical industry dissolvent residual is provided.
The object of the present invention is achieved like this: a kind of multilayer composite packaging material for edible salt is characterized in that: it constitutes by three layers on the white craft paper in top layer, middle polyethylene adhesive layer and inner layer polyethylene layer are compound.
Compared with prior art because the present invention adopts polyethylene to make adhesives white craft paper in top layer and inner layer polyethylene are bonded together, thereby do not contain benzene in the material, harmful chemical industry dissolvent residuals such as fat, ketone, meet the requirement of food hygiene.
Description of drawings:
Fig. 1 is a multilayer composite packaging material for edible salt structural representation of the present invention.
Fig. 2 is the production process scheme drawing of multilayer composite packaging material for edible salt of the present invention.
The specific embodiment:
Referring to Fig. 1, Fig. 1 is a multilayer composite packaging material for edible salt of the present invention.Constitute by 5 three layers on the white craft paper 3 in top layer, middle polyethylene adhesive layer 4 and inner layer polyethylene layer are compound.For indicating the product of packaging, can be at white layers of kraft paper 3 surface coverage ink printing layers 2.For heat-resisting, damp proof, can be at the high temperature resistant paper waterproof of ink printing layer 2 surface coverage gloss oil layer 1.
Referring to Fig. 2, the present invention produces by following technology: the polyethylene that molten condition is housed in drenching film machine 6, pair roller 7 and winding up roller 8 are located at pouring film machine 6 belows, the both sides of pair roller 7 are respectively equipped with white ox-hide paper bowl 9 and polyethylene film roller 10, when craft paper and polyethylene film are involved in pair roller in the opposite direction in vain, pouring film machine drenches the molten polyethylene that and is distributed between white craft paper and the polyethylene film, after cooling is solidified, coherent material forms MULTILAYER COMPOSITE salt packing of the present invention through the winding up roller rolling by polyethylene.
