HDPE bottles plastic cartridges
HDPE bottles are plastic bottles produced by blow molding, injection molding and other processes using HDPE (high density polyethylene) as the main raw material. The following is a detailed introduction to HDPE bottles:I. Material properties
Chemical stability: HDPE bottles are insoluble in any organic solvents at room temperature, resistant to acid, alkali and various salts, good chemical stability.
Physical properties: HDPE material is non-toxic, odorless, its hardness, tensile strength and creep is better than low-density polyethylene, abrasion resistance, electrical insulation, toughness and cold resistance is also better.
Melting point and decomposition temperature: general HDPE melting point of 142 ℃, decomposition temperature of 300 ℃, the adjustable range of injection temperature is larger.
Second, the production process
HDPE plastic bottle production process mainly includes the following steps:
Raw material preparation: HDPE pellets are subjected to strict quality testing to ensure that there are no impurities and harmful substances.
Extrusion molding: raw material particles are fed into the extruder, through high temperature and high pressure to melt it, forming a continuous plastic tube (billet).
Blow Molding: The parison is fed into the blow molding machine, preheated to the proper temperature, and then blown into the desired bottle shape with high pressure air.
Cooling & Cutting: The blow molded bottles are cooled in a cooling unit to fix their shape and cut into individual products.
Quality checking and packaging: Quality checking is carried out through automated equipment to reject defective products, ensure the quality of the final product, and carry out cleaning treatment and packaging.
III. Application Fields
HDPE bottles are widely used in many fields because of its excellent chemical stability and physical properties:
Food packaging: used for packaging of beverages, condiments, edible oils and other food products.
Pharmaceutical packaging: used for packaging of drugs, health products, cosmetics and other products.
Chemical packaging: used for packaging of pesticides, chemical raw materials and other products.
Daily necessities: such as hand sanitizer, disinfectant, shampoo bottles and so on.
Fourth, price and market
The price of HDPE bottles varies according to capacity, shape, quality requirements and market supply and demand. According to the latest market offer, the price of HDPE bottles of different specifications and uses varies greatly, ranging from a few cents to a few dollars. In the market, HDPE bottles are favored by many manufacturers because of their strong recyclability and relatively low cost.
Five, environmental advantages
The recyclability of HDPE bottles is its important environmental advantages. With the enhancement of environmental awareness, more and more companies are focusing on the sustainability of packaging and environmental protection, HDPE bottles as a recyclable material, can be recycled and reprocessed to reduce the impact on the environment.
In summary, HDPE bottles have become one of the important products in the plastic packaging industry with its excellent chemical stability, physical properties, wide range of applications and environmental advantages.
