Plastic barrels of production process analysis

Plastic barrels of production process analysis

 

Plastic barrels of production technology, we all know that plastic bucket is mainly used for storage and transportation of various liquids, flammable and explosive dangerous goods with good packing effect. Its a little different from other packaged goods have not friable, does not rust, and light oil, resistant to corrosion good excellent features.

Plastic barrels of production material to use polyethylene, polypropylene, polyester and other plastic blow molding, injection molding, plastic molding, rotational molding is made.

The main raw materials to produce plastic barrels polyethylene (Polyethylene, PE), referred to as PE. The addition polymerization of ethylene polymer compounds. Polyethylene is the world recognized the best materials in contact with food. Non-toxic, tasteless, odorless, food packaging hygiene standards. Polyethylene film, light and transparent, with moisture, oxidation, acid, alkali, air tightness in general, excellent sealing properties. Known as "plastic flowers" reputation. Up to the amount of plastic packaging and printing, the most important material.

PVC-- PVC

PVC abbreviation PVC, the formula (CH2-CH2CL) n, a vinyl polymer is the most important category, is the world's second largest after the polyethylene plastic varieties. Production in the country in the first place in the plastic. In the printing industry, often with colored PVC calendered film and a transparent coating film produced books, folders, tickets and other cover packaging and decoration.

Shrinkfilm-- shrink film

Shrink Films (Shrinkfilm), is a stretch in the production process is directed by hot air treatment or infrared radiation will shrink thermoplastic film during use. After the heat treatment, the film will wrap in the packing material, maximum contraction during the cooling phase, and long-term preservation.

LDPE-- low density polyethylene

Low density polyethylene, referred LDPE is plastic packaging and printing industry in various countries the largest amount of variety. A specific gravity of 0.92 to 0.93, can float on water. Low crystallinity (60%), pressure 1000 ~ 3000kg / C ㎡ bulk polymerization, it is also called high-pressure polyethylene. At 23 ℃, the density is about 0.92. Poor calender molding, blow molding processing into suitable tubular film. Suitable for food packaging, fiber packaging products, daily chemical products packaging. Biodegradable plastic bags logo HDPE-- high density polyethylene

High density polyethylene, referred to HDPE. A density of 0.941 ~ 0.965g / cc. Low-pressure polymerization, so called low-pressure polyethylene. Milky white, show poor gloss. Processing film can blow molding method and T-die extrusion process. Heat resistant to cooking, freezing cold resistant, moisture-proof, anti-air, isolated performance, not easily damaged, twice the strength of LDPE. Easy opening. Quasi paper is strong, as "quasi paper plastic film."

BOPP-- biaxially oriented polypropylene film

Biaxially oriented polypropylene film, also known as biaxially oriented polypropylene film, the English abbreviation code BOPP, which is characterized by the tensile molecular orientation, mechanical strength, folding strength, gas density, moisture barrier properties superior to ordinary plastic film. And cellophane unit area compared to the unit price is lower than cellophane. Since this film is excellent in transparency, in India after exceptionally bright and beautiful color reproduction is an important base plastic composite flexible packaging.
