Multi layer vacuum inner bags are widely used in scenarios that require long-term storage, moisture resistance, oxidation resistance, and pollution prevention due to their high barrier properties, puncture resistance, corrosion resistance, and good sealing performance. The following are its main application areas and characteristics: 1、 Food and agricultural products field 1. Meat and aquatic pr
The reason why PET plastic bottles are suitable for large-scale production is mainly due to their comprehensive advantages in material properties, processing technology, cost advantages, and market demand matching. Analyze from six key dimensions: 1、 Stable supply of raw materials and controllable costs 1. Wide range of raw material sources The raw materials for PET production are purifie
In the field of packaging, sustainable spray is a spray technology and related packaging solutions committed to reducing environmental impact and achieving sustainable development. It is mainly reflected in the following aspects: 1. Material selection Use of lightweight materials: The use of film or paper to make aerosol containers can greatly reduce the use of plastic or metal in packagin
PE plastic bottles, also known as polyethylene plastic bottles, have been widely used in the food and beverage industry due to their excellent chemical stability, low temperature resistance, flexibility, and non-toxic and odorless characteristics. The following are some common application scenarios: 1. Drinking water packaging: Whether it is bottled drinking water or buckets for bottled drinking
Multi layer vacuum inner bag is a packaging bag with a multi-layer structure used for vacuum packaging. It is composed of various materials with different functions, aiming to provide good protection and a longer shelf life for packaged items. Here is a detailed introduction about it: 1. Structural composition Outer layer: Generally made of materials such as polyester (PET), which have hig
PE plastic bottles have the advantages of chemical corrosion resistance, impact resistance, light weight, easy processing and molding, and relatively low price, so they are widely used in many industries. The following are some industries that use PE plastic bottles more: 1. food and beverage industry Drinking water: common bottled drinking water, whether it is bottled water in large barre
The injection molding process of PP cream can is a relatively complex process, mainly including the following key steps: 1. Raw material preparation: Select polypropylene (PP) plastic particles that meet food grade or cosmetic grade standards as raw materials. These particles should have good fluidity, thermal stability, and mechanical properties to ensure smooth molding during the injection mold
In addition to the above mentioned non reusable, high temperature avoidance and aging precautions, the following precautions should be taken when using PET plastic bottles: 1. avoid direct sunlight: direct sunlight for a long time will raise the temperature of PET plastic bottles, accelerate the aging of plastics, and may also lead to deterioration of substances in the bottles. Therefore, it shou
PE plastic bottle is polyethylene plastic bottle. Its barrier performance is mainly reflected in the barrier ability to gas, water vapor and some solutes. The following is a detailed introduction: 1. gas barrier Principle: the molecular structure of PE plastic bottle is relatively compact and has a certain degree of crystallinity. The presence of crystalline regions makes it difficult for
The barrier performance of PP cream cans is mainly reflected in their ability to block substances such as oxygen, water vapor, and light, as follows: 1. Oxygen barrier Stable molecular structure: PP has a tight molecular structure and high crystallinity, making it difficult for gas molecules to penetrate its molecular gaps. When oxygen molecules attempt to pass through the PP tank wall, t
