Abstract
The utility model relates to the field of composite materials, in particular to a polypropylene composite material packaging box. A calcium plastic food packaging box provided with a hydrophilic composite layer on the outer layer comprises hard paper boards, wherein a packaging box body is defined by the hard paper boards in an enclosing mode. The calcium plastic food packaging box provided with the hydrophilic composite layer on the outer layer is characterized in that high-filling calcium carbonate polypropylene hard paper boards are adopted to serve as the hard paper boards; and a food grade polyethylene (PE) layer is attached to the inner side of each hard paper board, and when food is contacted in food packaging, food safety can be conveniently guaranteed. A hydrophilic silica coating is attached to the outer side of each hard paper board. The hydrophilic silica coating has hydrophilicity, and waterborne pigment can be printed. Therefore, through the design, an original printing process is permitted to be used continuously to carry out pattern printing.
Description
Technical field
The utility model relates to field of compound material, is specifically related to a kind of polypropylene composite material packing box.
Background technology
Existing paper package box often adopts carboard in a large number.Because carboard is to process after trees are cut down, therefore producing carboard need to expend a large amount of trees, very not environmental protection.Because the carboard access times are limited, need comparatively frequently to change in addition, therefore caused a large amount of timber wastes.
Had now in addition the people that high calcium carbonate filled polypropylene is used for carboard, but because high calcium carbonate filled polypropylene material mechanical strength low, be not easy to the reason such as printing, be difficult to popularize in a large number.
The utility model content
The purpose of this utility model is, the calcium that provides skin to be provided with hydrophilic composite bed is moulded food package box, solves above technical matters.
The technical matters that the utility model solves can realize by the following technical solutions:
Skin is provided with the calcium of hydrophilic composite bed and moulds food package box, comprises carboard, surrounds a packaging box body by described carboard, it is characterized in that, described carboard is for adopting high calcium carbonate filled polypropylene carboard; Described carboard inboard is attached with layer food level PE layer.
So that when packaged food, when Food Contact, guarantee food security.
The described carboard outside is with a wetting ability silica dioxide coating.
The wetting ability silica dioxide coating has wetting ability, can print aqueous pigment.Therefore by this design, can allow to continue to use original typography, carry out the pattern printing.
The material component of described high calcium carbonate filled polypropylene board material is: 40～50 parts of acrylic plastering, 5～10 parts of polyethylene matrixes, 800 orders ~ 50 ~ 60 parts of 2500 order nanometer grade calcium carbonates, 0.5～1 part of coupling agent, 3 ~ 5 parts of elasticizer, 3 ~ 5 parts of ultraviolet absorbents.
Adopt the carboard of above-mentioned technology, have that cost is low, environmental protection, the advantage such as can reuse.Do not contain vegetable fibre in the utility model, the main material that adopts all can re-use repeatedly.Therefore be a kind of recyclable materials repeatedly.
Description of drawings
Fig. 1 moulds the side-looking structural representation of food package box for the outer calcium that is provided with hydrophilic composite bed;
Fig. 2 is the carboard structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, Fig. 2, the calcium that skin is provided with hydrophilic composite bed is moulded food package box and is comprised carboard 1, surrounds a packaging box body 2 by carboard 1.The carboard inboard is attached with layer food level PE layer 5.So that when packaged food, when Food Contact, guarantee food security.
The material component of high calcium carbonate filled polypropylene board material is: 40～50 parts of acrylic plastering, 5～10 parts of polyethylene matrixes, 800 orders ~ 50 ~ 60 parts of 2500 order nanometer grade calcium carbonates, 0.5～1 part of coupling agent, 3 ~ 5 parts of elasticizer, 3 ~ 5 parts of ultraviolet absorbents.Adopt the carboard 1 of above-mentioned technology, have that cost is low, environmental protection, the advantage such as can reuse.
Do not contain vegetable fibre in the utility model, the main material that adopts all can re-use repeatedly.Wherein polypropylene, nanometer calcium carbonate, all can re-use repeatedly.Therefore be a kind of recyclable materials repeatedly.
Above demonstration and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
