Description
Technical field
The present invention relates to field of plastic products, specifically a kind of plastic packing box and its production technology.
Background technique
Box-packed packing container made of plastics has various features, the appearance such as small density, light weight, easy to process can be saturating
It is bright can also be opaque, be widely used in food packaging industry.
Existing disposable plastic packing box has some problems in use: a. box cover is easily separated with box body, is led
It causes article in box to be scattered, to improve fastness, needs to be attached box cover and box body by staple or other tools；B. make
After box cover and box body being fixed with staple, increase the difficulty for opening packing box, and staple is easy to scratch hand；C. it carries out
When stacking campaign, since road jolts, the packing box of stacking is easy to collapse, and stability is poor.
And in the production process of plastic packing box, including mixing, injection molding, demoulding, cutting and stacking and etc., wherein
In cutting process, since process velocity is fast, it is difficult to guarantee the accurate of cutting position, cutter easily causes plastic packing box surface
Damage, rejection rate is higher, increases production cost to a certain extent.
Application No. is 201711141538.4 Chinese invention patents to provide a kind of plastics package with from sealed adhesive tape
Box, by being sealed from sealed adhesive tape to plastic packing box, to prevent box cover from scattering；Application No. is in 201810593170.3
State's patent of invention provides a kind of plastic packing box, by the cell wall tight fit of hard sealing strip and seal groove, improve cover board with
The sealing performance of box body.Above-mentioned two patent can improve sealing fastness to a certain extent, but for disposable
Production cost is higher for plastic packing box, and practicability is lower, and can not solve the plastic packing box transportation stability of heap poststack
The problem of difference.
Summary of the invention
In order to make up for the deficiencies of the prior art, the present invention provides a kind of plastic packing box and its production technologies.
The present invention to be solved the used following technical scheme of its technical problem to realize: a kind of plastic packing box, including
