Description
Technical field
The utility model belongs to technical field of macromolecules, and in particular to a kind of composite plastic of polypropylene container.
Background technology
Polypropylene (PP plastics) is the another fine resin kind developed after nylon, and it is a kind of high density, without side
Chain, highly crystalline linear polymer, there is excellent combination property.It is white translucent when uncolored.Food grade PP is exactly can
Directly to contact the plastics of food (product).
Existing plastic bowl is typically made of food-grade PP raw materials, but with consumer to health attention degree increasingly
Improve, people pay close attention to PP plastic bowls in itself material used whether health, health, safety, but also require that plastic bowl is durable,
Have a superior impact resistance, weight or when hitting it is not easily broken, will not leave behind scratch.
Although existing plastic bowl is made of food-grade PP raw materials, but microwave, but in order to attractive in appearance, coloring can be used
Agent, and after microwave heating, plastic bowl is very hot, it has not been convenient to takes.
Utility model content
In order to solve the above problems, the utility model provides a kind of composite plastic of polypropylene container, including container bottom and appearance
Wall, the container bottom and chamber wall form open ended cavity, and the container bottom includes protective layer I, substrate layer and protective layer
II, the chamber wall includes protective layer I, substrate layer, foaming layer and protective layer II；Wherein substrate layer is colored PP, the protection
Layer I and protective layer II are primary colors PP, and the foaming layer is PP microporous foams.
Preferably, the thickness of the protective layer I and protective layer II is 0.1-0.4mm, and the thickness of the foaming layer is 0.6-
1.0mm, the thickness of the substrate layer is 0.4-0.6mm.
Preferably, in addition to insulation cover, be detachably fixed connection between the insulation cover and chamber wall, the insulation cover with
Chamber wall contact position is provided with groove, and elastic seal ring is provided with the groove.
Preferably, it is to be threadedly coupled between the insulation cover and chamber wall.
Preferably, it is to snap connection between the insulation cover and chamber wall.
Preferably, the chamber wall is provided with least one set and is symmetrical arranged oblique neck, and the neck top is equipped with
Multiple latches, the insulation cover are provided with the card convex being engaged with latch.
The utility model beneficial effect：
（1）Using colored subtrate layer and primary colors protective layer, it can both meet the plastic products requirement attractive in appearance to color, again might be used
Ensure that no colouring agent etc. contacts with food, ensure safe and healthy.
（2）The PP microporous foam layers being provided with, there is excellent microwave adaptability, while have good heat-proof quality again, can
It is processed into various food containers.
（3）The insulation cover and vessel being provided with, it is possible to provide more permanent heat insulation effect.
