Plastic Contianer Rebound Performance

Plastic Contianer Rebound performance

The future direction of plastic development

Now we all know that can not degrade the plastic has become a source of environmental pollution. Worse, these we call the plastic components of the monomer, from the ancient oil can not be recycled.

However, the enzymes and catalysts used in the production process, which make this situation begin to change. Now used in daily life care package, cosmetic packaging, transparent plastic containers. In the future development of science and technology may be such as biogas and other renewable energy into the manufacture of plastic and synthetic rubber, the main components.

In the production or the original fossil raw materials, and these materials will become sustainable, but only to solve some of the problems. If these materials can be biodegraded, otherwise, they are still a problem for the environment. Winter explosion and toughness

At present, the final packaging of plastic containers is to use its mechanical properties to ensure that the packaging is not damaged, the chemical packaging of plastic containers to have the mechanical properties of compression, impact resistance, bending resistance, etc., mainly according to the nature of the product to be packaged of. In general, plastic containers must have a certain degree of stiffness to ensure that the packaging of the product as a whole intact, but also need to have a good rebound performance, so that after the squeeze back to the original form. In the case of the same material and wall thickness, stiffness and resilience is in fact a pair of contradictions, to meet the needs of customers, it is only for both.

The temperature of the plastic container is related to the material selected, the material is temperature resistance, dimensional stability, resistance to environmental stress cracking and other factors. Only by ensuring the long-term performance of plastic containers in order to ensure the quality and safety of the contents. Winter explosion-proof pipe, you need to adjust the plastic container formula structure, the use of enhanced toughness of the material to improve the impact resistance of plastic containers. Commonly used materials 【Cosmetics plastic containers】

The material of plastic containers is usually PET, PE, K material, AS, ABS, acrylic, etc., usually used for cosmetic containers wall thicker cream bottles, caps, corks, gaskets, pump head, dust Hood for injection molding; PET blowing for the two-step molding, tube embryo for injection molding, finished packaging for the blown. Others such as container wall thinner emulsion bottle, washing bottle for blowing. PET material for the environmentally friendly materials, with high barrier, light, not broken characteristics, resistance to chemical resistance, transparency is extremely strong, can be made pearl, colored, magnetic white, transparent, widely used in the installation of jelly water. Bottle is generally standard 16mm, 18mm, 22mm, 24mm caliber, can be equipped with pump head. Acrylic material for the injection molding bottle, chemical resistance is poor, generally can not directly install the paste, with a liner barrier, filling is not easy to prevent the paste into the liner and acrylic bottles between, so as not to The occurrence of cracks, transport packaging requirements are higher, because the scratches look particularly obvious, high permeability, feeling the wall is particularly thick, but the price is very expensive. AS, ABS: AS transparency is better than ABS, and toughness is better.
