The main raw material for the production of plastic barrels is polyethylene (PE), which is a high molecular organic compound formed by addition polymerization of ethylene. Polyethylene is recognized as the best food contact material in the world, non-toxic, tasteless and odorless, and meets the hygiene standards for food packaging. Polyethylene film, light and transparent, has the properties of moisture resistance, oxygen resistance, acid resistance, alkali resistance, general air tightness, and excellent heat sealability. Material. Secondary water supply in high-rise buildings, water storage, water treatment, medicine and food, electronic chemical industry, aquaculture, textile printing and dyeing, petrochemical reagents, pickling and electroplating, brewing sugar, vegetable pickling, refrigeration, environmental protection and hygiene and other industries widely used in.
Metal pails are larger capacity containers made of sheet metal. Its specifications include small open head pails, middle open head barrels, carrying barrels, special-shaped top barrels, full-opening conical steel barrels, full-opening barrels, straight-opening barrels, opening necked steel barrels, and so on. It has a very wide range of applications, involving many industries such as food, beverage, chemical, aerosol and other content packaging. In order to meet the needs of these packagings, metal drums have various properties suitable for them, among which the sealing properties are common and very important. Compared with other packaging materials, metal materials are denser, stronger, easier to form and process, and metal drums have better sealing performance, which can be suitable for long-term storage of food and items that meet high requirements such as leak-proof, anti-corrosion, and pressure resistance. , because the application field of metal barrels is very wide and has an irreplaceable status.
The closed-mouth square pail is mostly made of polyethylene, polypropylene, polyester and other plastics by blow molding, injection molding, blister molding, and rotational molding. It is mostly used to hold liquids and solids in chemical, pesticide, medicine, food, hardware electronics, electromechanical and other industries. The pail contains the following features: light weight, high temperature resistance, not easy to corrode, clean and clean, reduce pollution, can be tilted 20 degrees, easy to transport and stack, save space. The PE plastic square pail is easy to use, economical and durable, and can contain Class II and III dangerous goods. It has been widely used in the storage and transportation of various chemicals such as coatings and pesticides. PE plastic square barrel products have the following characteristics: 1. The use of IBC ton barrel packaging can greatly reduce the cost of production, storage, transportation and operation, and save a lot of manpower and material resources; 2. The product structure is reasonable, firm and strong, can be directly loaded and unloaded by forklift, and can be stacked and stored; 3. The bottom of the product is equipped with a drain valve, which is convenient, rapid, thorough and safe for liquid discharge, easy to clean, and can be used for multiple turnovers, saving energy and environmental protection; 4. It has beautiful appearance, non-toxic, tasteless, HDPE material, food grade, acid resistance, alkali resistance, impact resistance, high temperature resistance, cold resistance. It can be used in the chemical industry and is easy to install and transport.
A steel can, tin can, steel packaging, or can is a container for the distribution or storage of goods, made of thin metal. Many cans require opening by cutting the "end" open; others have removable covers. They can store a broad variety of contents: food, beverages, oil, chemicals, etc. Steel cans are made of tinplate (tin-coated steel) or of tin-free steel. In some dialects, even aluminium cans are called "tin cans". Most cans are right circular cylinders with identical and parallel round tops and bottoms with vertical sides. However, cans for small volumes or particularly-shaped contents, the top and bottom may be rounded-corner rectangles or ovals. Other contents may suit a can that is somewhat conical in shape. Fabrication of most cans results in at least one rim—a narrow ring slightly larger than the outside diameter of the rest of the can. The flat surfaces of rimmed cans are recessed from the edge of any rim (toward the middle of the can) by about the width of the rim; the inside diameter of a rim, adjacent to this recessed surface, is slightly smaller than the inside diameter of the rest of the can.
