How are Plastic Bottle produced

Along with the unceasing enhancement of environmental consciousness, the plastic bottle manufacturer for bottled consumption, resist all very quickly, especially in Europe and the United States this higher voice, to a certain extent, reduces the consumption of plastic market, instead of other packaging materials. Some experts argue that it is used to encapsulate glass bottles. In trading data over a period of time of Plastic Bottle and Plastic Bottle of market operation time is summarized, and future prospects in Plastic Bottle is optimistic, but the development of China's many small and small and medium-sized plastic manufacturers are faced with many challenges. The use of Plastic Bottle advocates the use of less green raw materials, and USES the same materials as possible, detachable and coexisting materials, as simple as possible, easily recycled materials. At the same time, the production quantity of waste is minimized, and the development trend of light packaging film is put forward. The key to the development of plastic stabilization technology is to study development and application agents, prepare antioxidant agents, uv stabilizers and free radicals to capture new ones. The plastic containers, food pallets or turntable containers that are refilled by daily chemical industry can be used in plastic stabilization technology and high quality of plastic products to improve their reuse or recycling value. Strong market price of Plastic Bottle, the recent crude oil shock, merchants mentality is supported, but over a period of time to adapt to the development of it, markets wait-and-see atmosphere is strong, the price of petrochemical implementation difficulties, market prices, prices continue to moderate At present, the shape of the Plastic Bottle have a round, square, oval in shape. The volume of the round bottle is the largest, its characteristic is the wall thickness uniformity, the impact energy absorption capacity is higher, the production cost is lower, but the effective area that the utilization rate is low, the storage or transportation. The storage square or rectangular effective area, with high efficiency, good stability, but prone to expansion. The size of the plastic bottle, there is no definite regulation, usually according to the user's needs and the nature of the drug. In addition to the capacity of the nominal capacity of the plastic bottle, and sufficient capacity, it is more specific than nominal capacity, and the specific requirements are the diameter of the bottle mouth and bottle height. Taking small and medium-sized enterprises as an example, the analysis of structural characteristics can be clearly seen from the bottle neck, shoulder, bottle body and other fields.

At present, China's packaging industry has developed rapidly, especially in plastic packaging, how to mention Plastic Bottle, everybody is not strange, can be seen everywhere in our daily life of the use of Plastic Bottle, for example, beverage, medicine, spices and so on all is the use of Plastic Bottle for packaging. Plastic bottle has a strong competitive advantage in choosing packaging materials. This is mainly reflected in the following aspects:

On the one hand, the choice of Plastic Bottle is approved by the national quality certification agency. On the other hand, in terms of material Plastic Bottle mainly produce plastic as raw materials, to produce the most prominent feature of plastic is light weight, not afraid to fall, so plastic bottle with its unique competitive advantage has been widely used in various fields. For example, in the medical field, Plastic Bottle are the main drugs packaging equipment, solid or powder medicine, in particular, more than in the form of plastic packaging, not only can guarantee the safety of medicines, and to use the cost would be greatly reduced.

How do Plastic Bottle come out, what process does plastic bottle have?

Plastic Bottle when production has a certain production technology and method of plastic processing methods including: crowded blowing, injection molding, calendering, blow molding, die, laminating, casting, such as a variety of ways.

Plastic Bottle are produced. There are two types of Plastic Bottle.

The first is a crowded blowing process, the plastic raw materials to join in the extruder, by heating the molten plasticizing extruder melting parison, add the bottle blow molding mold, cooling stereotypes from the mold after, in addition to scrap edge after finished product. This process is mainly used to produce polyethylene and PVC Plastic Bottle, such as milk bottles and pickles.

The second kind is the injection process, the plastic raw material is injected into the injection molding machine for injection moulding, and then put into the bottle mould to draw the injection molding, and then the finished product is cooled. This process is mainly used to produce PET Plastic Bottle, such as mineral water bottles.

How do Plastic Bottle come out, what process does plastic bottle have? Plastic Bottle is passed, blow molding, plastic heating melt, then pressed into a special blow molding mold and the internal air pressure, pressure, mold plastic, forming the shape of the final product, because the shape of the bottle to the external pressure of time, so the emphasis is on the bottle itself inward, heating temperature reaches a certain degree, will soften plastic, pressure resistance is smaller, so the bottle will become smaller and smaller.
