PE rubber bag: The appearance does not look very transparent, it has a turbid feeling, and the toughness is better. Many hand -held rubber bag raw materials are made of PE material, and there are very large -scale industrial use rubber bags. The use is relatively wide. The thinnest thickness of the PE rubber bag can be 1c, and even a little thinner. Many barrel water packaging belongs to that category. PO gum bag: good tension, high hardness, and slightly lower transparency than other plastic bags. Because the tension is better, it is widely used in shopping malls and hotel industries. Most of the vests are made of PO materials. PVC gum bag: The texture is soft, and the thickness of the general use is thicker than the thick -blown rubber bag. PVC rubber bags have more manual composition. It has not yet been formed by a automated production line, unlike the production of other meta -line rubber bags. Therefore, there is still a certain profit space for the price. Because PVC rubber bags are not environmentally friendly materials, there are certain restrictions on certain industries. PP rubber bag: It is a relatively transparent one in the rubber bag of the film. Generally, there are more outsourced packages for products. opp rubber bag: The texture is crispy and high, and the brightness is high. If there is no gap, it is difficult to tear it open, but there is a little gap that can be torn out without any strength. If the machine is not adjusted when cutting, or it is easy to explode when there is a problem with the raw material, but if the items are not specially required, there are generally no problems. There are two forms of the sealing side. The line is sealing, and the other is the sealing of the explosion -proof edge. In fact, the two methods are the same when they are produced, but they are because of the positive and anti -knife. Specifies, then print it if there are printing. If you do n’t print it, you will directly fold it. Add sticky glue and white pearl film according to the requirements of the order. , Then packaged. The scope of application of OPP rubber bags, elephant cards, accessories, leather goods, clothing, etc. can often see the traces of OPP rubber bags.
PVC-Polyvinyl chloride The polyvinyl chloride referred to as PVC, molecular formula is (CH2-CH2) n, which is the most important category of ethylene polymer. Variety. -shrinking film The contraction film () is a thermoplastic plastic film that is stretched by stretching during the production process, during use or infrared irradiation, which will shrink. After thermal treatment, the film is wrapped tightly on the packaging material. The contraction force reaches the maximum value during the cooling stage and can be stored for a long time. LDPE-low-density polyethylene low-density polyethylene, referred to as LDPE is the largest variety of plastic packaging in various countries [1] printing industry. The gravity is 0.92 to 0.93, which can float in water. Low crystalline (60%), the ontology aggregation is performed at the pressure of 1000 ～ 3000kg/c㎡, so it is also called high -voltage polyethylene. At 23 degrees Celsius, the density is about 0.92. Suitable for food packaging, fiber products packaging, daily necessities packaging.
Commonly used food packaging plastic bags are mostly made of polyethylene film. The film is non -toxic, so it can be used for food. Another type of film is made of polyvinyl chloride, and polyvinyl chloride itself is also non -toxic, but the additives added according to the use of the film are often harmful to the human body and have certain toxicity. Therefore, such thin films and plastic bags made by the film should not be used to make food. It can also be stuck to make it easy to operate. The polyethylene (,, PE) is referred to as PE. It is an organic compound of polymer for ethylene. Polyethylene is the best ingredient of food in the world. Non -toxic, odorless, odorless, meet food packaging sanitary standards. Polyethylene film, light and transparent, has a general performance such as moisture -proof, antioxidant, acid resistance, alkali resistance, qi density, and excellent thermal sealing. It is the most important and most important material for plastic packaging.
