Description
Technical field
The utility model relates to barrier container, it is specifically for use in the container for containing food, drug and chemical products.
Background technique
With the improvement of people's quality of life, it is continuous that the requirement that especially food is stored or packed is stored or packed to product
Improve, in order to the guaranteeing the quality of food, it is fresh-keeping, protect flavor and Shelf-life, be developed high-barrier packaging material.
There are three types of blocking methods on the market now:
1. three layers altogether note or multilayer be total to note: three layers note or multilayer are infused all altogether altogether is to be injected with pp (polypropylene) wherein, cover half
After the cooling of two wall of dynamic model, EVOH (ethylene/vinyl alcohol copolymer) is injected to point cooling time, is formed and is obstructed in middle layer.
2. multi-layer co-extruded: being formed and obstructed with aluminizer, barriering effect is higher than EVOH.
3. our IML aluminium foil film: cpp (injection molding pp fusion) aluminium foil film+transparent nylon (food-grade)
Side mark: in cover half；
Bottom mark:
1. millimeter paper is placed on mavable module core, millimeter paper is in cup bottom inner portion；
2. millimeter paper is placed on fixed mold core, millimeter paper is outside cup bottom end；
Barriering effect: IML aluminium foil film > aluminizer > EVOH.
Since, there is hydroxyl, EVOH resin has hydrophily and hygroscopicity in the molecular structure of EVOH resin.Work as absorption
After moisture, the barrier property of gas, which will receive, to be significantly affected.In the environment (50%RH or more) of high humidity, the barrier property of EVOH
It declines to a great extent.Aluminizer has excellent folding resistance and good toughness, pin hole and breach seldom occurs, and no flexure cracking is existing
As, therefore the barrier property of gas, water vapour, smell, light etc. is improved., using aluminium foil film, barrier property is more preferable for we, uses
In-mold label plays high-barrier in all directions.
Utility model content
