There are many types of food Pet Bottle Preform, including glass bottles, metal cans, packaging boxes, and PET bottles. The performance requirements of the packaging box are: regenerability, effective use of space, weight, etc. In addition, the packaging box has a special feature, that is, through the research of the layered structure of the packaging box, various blocking properties such as light blocking property and oxygen barrier property are obtained. easy to accomplish.
- Package structure that meets quality requirements
In addition to transparency, the package can be configured to meet its functional requirements through its structure and material composition. According to the shape, the representative package includes a box structure box, a square box, and other structural boxes.
As a representative package, there are a milk box and a cool package of a roof box structure, etc. The paper jam used is selected from 250 g/m 2 to 400 g/m 2 depending on the size, shape and contents of the package. The cardboard used for these milk packages is made by extrusion molding of polyethylene on the front and back sides of the cardboard by an extruder. Since paper and polyethylene are relatively easily peeled off or separated in an alkali solution, regeneration of paper components is easily achieved. The recycling of milk packaging can be realized. In addition to the above-mentioned factors that the paper component is easy to regenerate, there is also a reason that only the original pulp is used to produce the cardboard for the packaging.
3. Various barrier properties
Oxygen, water vapor, and light are the causes of deterioration in the contents of the package. One of the methods to add the relevant barrier properties to the package is to compound it with aluminum foil. According to this method, the package can be provided with a function of blocking oxygen, water vapor and light. The aluminum foil composite packaging box allows the contents to be preserved for a long time.
4. Environmental protection
The use of aluminum foil provides a possibility for long-term preservation of the packaged food, but it may cause difficulty in regeneration of the base paper, and may also cause an accident in which the aluminum foil in the incinerated paper container damages the incinerator. By using barrier materials that replace aluminum foil, comprehensive requirements that are both environmentally friendly and long-term can be achieved. Typical alternatives are barrier materials such as EVO and silicon vacuum coating.
Food pet bottle preforms are made of polyethylene material in the innermost layer from the viewpoint of molding and cost. It can reduce the absorption of juice by the polyethylene material, thus maintaining the fresh taste of the juice.
