What are the characteristics of PE plastic bottles
PE plastic bottles, also known as polyethylene plastic bottles, have the following characteristics:
1. In terms of physical performance
Lightweight texture: PE plastic bottles have a lower density, usually between 0.91-0.96g/cm 3, much lighter than many other materials such as glass bottles, metal bottles, etc., making them easy to carry and transport.
Good flexibility: It has good flexibility and extensibility, is not easy to break, can withstand a certain degree of compression, bending, and stretching without damage, and is suitable for packaging products that require soft containers, such as shampoo, shower gel, etc.
Diverse Transparency: Its transparency can vary depending on the production process and additives, from completely opaque to semi transparent or even high transparency, meeting the requirements of different products for packaging appearance.
Moderate barrier performance: It has certain barrier properties against moisture, gases, etc., which can prevent the volatilization and leakage of contents, as well as the entry of external air and moisture to a certain extent. However, the barrier performance is relatively weak compared to some special materials such as polyester (PET).
2. In terms of chemical properties
Good chemical stability: able to withstand corrosion from various acids, bases, salts, and solvents, insoluble in most known solvents at room temperature, and can be used to package various chemically stable items such as detergents, cleaning agents, and some pesticides.
Strong water resistance: Its performance remains unchanged after long-term contact with water, and it will not deform or deteriorate due to water absorption. It is suitable for packaging liquid products containing water.
Good antioxidant properties: Under normal use and storage conditions, PE plastic bottles are not easily oxidized and can maintain good physical and chemical properties, extending the shelf life of packaged products.
3. In terms of processing performance
Easy to shape: Various molding processes such as blow molding, injection molding, extrusion, etc. can be used to easily process bottles into various shapes and sizes to meet the packaging needs of different products, such as circular, square, irregular, etc. Different specifications of bottle mouths, caps, etc. can also be made.
High production efficiency: Short molding cycle, fast production speed, capable of large-scale industrial production, reducing production costs, improving production efficiency, and meeting the large demand for packaging products in the market.
Good surface treatment performance: It is easy to carry out surface treatment processes such as printing, coating, and labeling. It can print exquisite patterns, text, and labels on the bottle body, improve the beauty and recognition of the product, and promote product sales.
4. In terms of safety and environmental performance
Non toxic and harmless: PE plastic is non-toxic and odorless, meets food hygiene and safety standards, and can be directly used for packaging food, drugs, health products, etc., without harm to human health.
Recyclability: Belonging to recyclable plastics, discarded PE plastic bottles can be recycled and reused through steps such as cleaning, crushing, melting and granulation to produce new plastic products, achieving resource recycling and reducing environmental pollution caused by waste.
Degradability: Some PE plastic bottles have a certain degree of biodegradability. After a certain period of time in the natural environment, they will gradually decompose into harmless substances, reducing their long-term impact on the environment. However, their degradation rate is relatively slow.
5. In terms of cost and economic performance
Low production cost: Compared with glass bottles, metal bottles, or some high-performance plastic bottles, PE plastic bottles have relatively low raw material and processing costs, making them highly competitive in the market and able to reduce packaging costs for enterprises.
High cost-effectiveness: Taking into account its physical, chemical, and processing properties, as well as its low cost, PE plastic bottles have a high cost-effectiveness, which can meet the packaging needs of products while bringing good economic benefits to enterprises and consumers.
