According to their own properties, plastics packaging can be divided into two categories: thermoplastics that can be melt-molded repeatedly and can basically maintain their characteristics and thermosets that can only be melt-molded once. According to its use, it can be divided into general plastics with wide application range, low price and good comprehensive performance, such as PE, PP, PVC, PS, and amino plastics with good physical and mechanical strength, and may be used in engineering machinery instead of metal. Engineering plastics such as: ABS, nylon, polyester, POM, TPX-1, etc. And a class of engineering plastics with particularly excellent performance, such as special plastics with particularly good radiation resistance and high temperature resistance, such as polyarylsulfone, liquid crystal polymer, etc. According to the molecular crystal size of thermoplastic resins, thermoplastics can be divided into amorphous polymers and crystalline polymers.
Main features
The main characteristics of plastic are:
First, the density is small, the specific strength is high, and a higher packaging yield can be obtained, that is, the “package volume or packaging area per unit mass.”
Second, most plastics have good chemical resistance, good acid resistance, alkali resistance, resistance to various organic solvents, long-term storage, and no oxidation.
Third, the molding is easy, and the required molding energy consumption is lower than that of metal materials such as steel.
Fourth, it has good transparency and easy coloring.
Fifth, it has good strength, high strength per unit weight, impact resistance and easy modification.

4 Common Food Packaging Materials
When people buy food products, they don’t always think about the packaging that their food comes in. But packaging is an important thing to think about. Food packaging serves many purposes, including preserving the food and protecting it from external elements. However, among the people who do pay attention to food packaging, more people are trying to buy eco-friendly packaging options. In fact, a 2016 West Rock Consumer Survey found that 45% of consumers bought a product due to the environmentally friendly packaging. Because there is so much packaging wasted, it’s important to have green packaging options. This article is going to take a look at some of the benefits of common food packaging materials.
Paper packaging: Paper is a very versatile packaging product. Thicker products like paperboard and fiberboard are commonly used. But paper can also be used to make thinner packaging products like box labels, paper bags, and more. Although it has a variety of applications, paper is not often considered an environmentally-friendly option among the retail packaging options.
Plastic packaging: Plastic is typically found in the form of bags or containers. This packaging material is used to hold frozen foods, snacks, dry goods, and dairy products. It can also be found in bottle form and used for drinks and condiments. Because plastic is recyclable, it’s considered green packaging. In today’s society, green packaging options are becoming a more important consideration for consumers when choosing food products.
Glass packaging: Another green packaging material is glass. Glass packaging is often used for beverages or food products that may be stored for a long period of time. When recycled, it can be used to make additional glass packaging products. However, it’s not as easy to work with as some other packaging materials.
Aluminum packaging: As a common metal, aluminum is inexpensive, easily made, and can be environmentally friendly. Aluminum food packaging can be used to store food safely for a long period of time. Meats, vegetables, and beans are commonly stored as canned goods in aluminum. Aluminum is a common choice because it helps protects food products from moisture, sunlight, and other external elements.
While all of these packaging materials offer multiple benefits, plastic is still one of the most popular packaging choices. It’s easy to use and can be made in any shape or color, making it a popular choice for customizable packaging solutions. Reusable clamshell packaging is one of the most common choices in plastic packaging.
If you’re looking to buy food products, or implement new packaging into your company, consider going plastic. It’s an inexpensive, versatile option that many consumers will choose because of the multiple benefits it can offer.

What are the advantages of PET plastic blister packaging
PET blister packaging is mainly made of PET plastic, which is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer, and is a common resin in life. PET plastic has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120℃. It has excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good, but the corona resistance is poor. Creep resistance, fatigue resistance, friction resistance, and dimensional stability are all very good. PET will decompose under the action of strong acid, strong alkali and water vapor, and has good resistance to organic solvents and weather.
The advantages of PET blister packaging:
1. PET blister packaging has good mechanical properties, impact strength is 3-5 times that of its material packaging, and good folding resistance.
2. PET blister packaging has strong corrosion resistance and will not be corroded by oil, dilute acid, dilute alkali, etc.
3. PET blister packaging has excellent weather resistance and can be used for a long time in high or low temperature environments, and its mechanical properties are small at high and low temperatures.
4. The gas and water vapor permeability of PET blister packaging is low, and it has excellent gas, water, oil and odor resistance.
5. PET blister packaging has high transparency, can block ultraviolet rays, has good gloss, and can protect the product well.
6. PET blister packaging is non-toxic, tasteless, and has good hygiene and safety. It can be directly used for food packaging.
The development of domestic plastic packaging
Plastic packaging refers to plastic packaging. Plastics are mainly made of synthetic or natural polymer resins. After adding various additives, it has ductility at a certain temperature and pressure, and can fix its shape after cooling.
The process in which natural or synthetic polymer resin molecules are in a molten state and the auxiliary molecules are evenly distributed around it is called plasticization. Having reached this process is called plasticization, but has not reached it, and is considered to have not been plasticized. Plastic packaging is one of the four major materials in the packaging industry: paper and cardboard accounted for 30%, plastics accounted for 25%, metal accounted for 25%, and glass accounted for 15%.
According to the “2013-2017 China Plastic Packaging Industry Market Prospects and Investment Opportunity Analysis Report” statistics show that in 2011, the total industrial output value of the packaging industry was 929.639 billion yuan, and the total industrial output value of the plastic packaging industry accounted for the total industrial output value of the national packaging industry. Calculated by 10% of the output value, the total industrial output value of the plastic packaging industry in 2011 is estimated to reach 90 billion yuan, with the number of enterprises reaching 2,000. my country’s plastic packaging industry can produce more than 30 types of plastic packaging materials in six categories, which can basically meet the needs of the domestic pharmaceutical industry, with annual sales accounting for about 15% of the total plastic industry sales.
In the plastic packaging industry, there are few large-scale enterprises and state-owned enterprises, and many private enterprises are scattered. The overall scale of the industry is small. At the same time, it faces the market invasion of many foreign brands. For example, the German SCHOTT Group has entered the Chinese market with its strong technical and economic strength. During the Twelfth Five-Year Plan period, my country’s plastic packaging industry needs to be integrated. Through various means such as enterprise alliances, acquisitions, and mergers, some large-scale enterprises and joint enterprises will be formed to promote the healthy development of the industry.
With the rapid development of China’s economy, the improvement of people’s living standards and the increase in medical expenses caused by the aging population, the development of new drugs has increased, the pace of reform of the medical security system has accelerated, and the expansion of urban residents’ medical insurance, the plastics industry will continue to maintain The momentum of rapid growth. In addition, the quality of China’s plastic packaging materials and packaging varieties are significantly lower than international standards. In developed countries, plastic packaging accounts for 30% of the value of plastic products, compared to less than 10% in China. The next few years will be a period of rapid development of China’s plastic packaging industry.
The “Outline of the Twelfth Five-Year Development Plan for the Plastic Packaging Industry (Draft for Comment)” puts forward that plastic packaging is an important part of the plastics industry. Packaging materials and containers that directly contact drugs are the basic elements of pharmaceuticals, which are important for drug quality and drug safety. Have an important impact. Therefore, in the “Twelfth Five-Year Plan” for the plastics industry, plastic packaging should be placed in the same position as medicines, rather than supporting industries, and should be clearly defined in the national plastics industry plan. The research of plastic packaging materials should be synchronized with the development of medicines, and policy support for the plastic packaging industry should be strengthened to reflect the industrial policy of plastic packaging materials, key development product areas and technical fields, and development directions.
