Airless plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Beverage bottles are mostly plastic products. The two materials of polyethylene and polypropylene are non-toxic and tasteless. They are safe for the human body when used for filling beverages. However, once polyethylene is corroded by high temperature or acid, it will slowly dissolve and release organic solvents, which will cause harm to the human body.

For plastic bottles, various problems currently exist. Let's analyze it carefully. First of all, plastic bottles are a labor-intensive industry, and the current labor costs are rising. 


For plastic bottle companies, labor costs have become a huge pressure. Secondly, the prices of raw materials continue to rise. Due to the rise in various costs in the market, raw materials have risen significantly, which has put another layer of pressure on plastic bottle companies. 


Thirdly, with the European debt crisis and the weakening of the world economy, foreign trade orders for plastic bottles have gradually declined, and many foreign trade companies have moved to the domestic market, which has brought greater pressure to the already competitive domestic plastic bottle market. The war is getting fiercer and the profits of the enterprise are getting lower and lower.


For airless plastic bottle manufacturers, under the current various pressures, they should take the road of industrial upgrading, take the road of innovation in the field of plastic packaging, and strive to increase the added value of plastic bottles. Continuous improvement in all aspects of plastic bottle design, production and sales.


Pay special attention when using plastic products, do not touch vinegar, detergent, etc., avoid direct sunlight, high temperature, etc., to avoid chemical reactions. In addition, when you buy plastic tableware, you should choose plastic products with PE (polyethylene) or PP (polypropylene) labels, less decorative patterns, colorless, odorless, and smooth surface.

There are many ways to make polyethylene, and the most common one is to polymerize ethylene at a high temperature of 200-300°C and a pressure of 1000-2000 atmospheres. In polyethylene, no other substances are mixed. The polyethylene prepared in this way has low density, soft texture, and has high stability to sunlight, air, moisture and chemical reagents, so there is no need to add stabilizers and plasticizers, which are mostly stabilizers and plasticizers. Poisonous or highly toxic.

 

Features: Plastic bottles are easy to carry, not afraid of falling, easy to produce, and easy to recycle.
