HPMC is a water-soluble ether, with thermal gelation properties, which has excellent cold-water soluble and hot water insoluble properties, It is a non-ionic cellulose ether mixture, the solution of non-ionic charges, which can`t react with metal salts or ionic compounds. It has PH stability, strong enzyme resistance and metabolic inertia; also has a good dispersion, emulsification, thickening, adhesion, water retention and protective colloid properties, so they are which is widely used in construction, paint, synthetic resin , ceramics, tobacco, textile, daily chemical, petrochemical and electronics industries.
The main purpose:
1. Construction industry: As a water retention agent for cement sand slurry, the retarder makes the slurry pumpable. Used as a binder in plasters, gypsums, putty powders or other building materials to improve spreadability and extend maneuverability. Used as a paste tile, marble, plastic decoration, paste enhancer, can also reduce the amount of cement. The water retention of HPMC enables the slurry to not crack too quickly after application, and enhances the strength after hardening.
2. Ceramic manufacturing: widely used as a binder in the manufacture of ceramic products.
3. Coatings industry: As a thickener, dispersant and stabilizer in the coatings industry, it has good compatibility in water or organic solvents. Can be used as a paint remover.
4. Ink printing: as a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvent.
5. Plastic: as a mold release agent, softener, lubricant, etc.
6. Polyvinyl chloride: As a dispersant in the production of polyvinyl chloride, it is the main auxiliary agent for the preparation of PVC by suspension polymerization.
7. Other: This product is also widely used in leather, paper products, fruit and vegetable preservation and textile industry.

Today, online shopping has become a fashion and has been loved by many consumers. Plastic packaging companies should grasp the trend of industry development and focus on production. In general, the development of the plastic packaging industry mainly presents the following four major trends:
1, packaging lightweight
The trend toward lightweight packaging and light weight has led to the development of customized services for certain products. Flexible packaging products, including protective mail, foam packaging, air pillow packaging, paper-filled products, and packaging, will continue to be the first choice for online shopping product packaging due to their low cost and strong protection.
2, packaging protection
Protective packaging, especially air pillow packaging and mail packaging products, have played a huge role in protecting and avoiding the impact of goods from shock, vibration, wear and handling during transportation, and have been received by more and more online shop sellers. Chased.
3, packaging security
Many people cut the courier in order to save trouble by hand, but some people have allergies after the courier, and allergic symptoms such as itchy hands or redness. At present, the source of raw materials for domestic express packaging is relatively complicated, and it is mostly processed for domestic garbage and chemical materials. A large amount of harmful substances such as plasticizers and flame retardants remain, which may cause skin allergies. Some harmful substances enter the human body, and it is also possible to affect liver, kidney, bones, etc. through blood circulation.
4, packaging environmental protection
Foam-protected packaging, such as insulated shipping containers, molded foams, in-situ foamed polyurethanes, foam rolls, etc., will account for the second largest share of demand in the market, while rigid protective packaging products account for the smallest total demand, but Variable pricing structures are moving in a sustainable direction, and pulp molding and protective paperboard will benefit.
Plastic packaging has gradually evolved from food packaging to industrial packaging, pharmaceutical packaging, building materials packaging, cosmetics packaging, etc., and its scope and prospects will be more and more extensive. By understanding the development trend of the plastic packaging industry, companies can take advantage of the trend and enter the fast lane of development.
