A plastic bag making machine
mainly consists of: storage device, stepping device, frequency conversion device, whole bag device, heat sealing cutter and control device. The main feature is that the storage device stores the corresponding amount of raw materials, the stepping device drives the raw materials, the frequency conversion device drives the heat sealing cutter, the whole bag device is in the whole bag after the number of fixed bags is produced, and the heat sealing cutter controls the temperature through the temperature controller to control the raw materials. Sealing and cutting, the control device coordinates all aspects of the action. Next, let's take a look at the classification and use of plastic bag making machines, as follows:
Classification of plastic bag making machines:
Plastic bag making machines are generally divided into: high-pressure polyethylene plastic bags, low-pressure polyethylene plastic bags, polypropylene plastic bags, and polyvinyl chloride plastic bags.
Use of plastic bag making machine:
1, high-pressure polyethylene plastic bags for: food packaging: cakes, candy, roasted seeds and nuts, biscuits, milk powder, salt, tea, etc.; fiber packaging: shirts, clothing, needle cotton, chemical fiber products; Daily Chemical
2, low-pressure polyethylene plastic bags are mainly used for: garbage bags, strain bags; convenient bags, shopping bags, handbags, vest bags; fresh-keeping bags; woven bags inside the bag.
3, the use of polypropylene plastic bags are generally: for packaging textiles, needle cotton products, clothing, shirts and so on.
4, PVC plastic bags are mainly used for: gift bags, luggage bags, needle cotton packaging bags, cosmetic packaging bags; zippered file bags, information bags.
Inorganic Acid, also known as mineral acid, is a general term for acids in inorganic compounds. Inorganic acids are generally inorganic compounds that dissociate hydrogen ions. According to the composition, the inorganic acid can be divided into oxo acid, anaerobic acid, complex acid, mixed acid, super acid, etc. According to the degree of dissociation, it can be divided into strong acid and weak acid, and according to the hydrogen ion which can be ionized in the molecule. The number is divided into monobasic acid, dibasic acid and polybasic acid. Most inorganic acids are used to provide hydrogen ions.
