Rubber and plastic packaging is a packaging material made of rubber and plastic as the main raw materials through thermoplastic or thermosetting processing technology. It is widely used in food, medicine, daily chemicals, electronics, machinery and other industries. With its excellent sealing, cushioning, corrosion resistance and other characteristics, it plays an important role in protecting products and extending product life. The definition of rubber and plastic packaging covers its raw materials, processing technology and application areas, aiming to provide consumers with safe, reliable and environmentally friendly packaging solutions.
Application areas of rubber and plastic packaging industry:
1. Food packaging is one of the most widely used areas of rubber and plastic packaging. Rubber and plastic packaging materials can effectively protect the freshness and taste of food and prevent food from being contaminated due to their good sealing, barrier and temperature resistance. In food packaging, rubber and plastic materials are often used to make packaging bags, turnover boxes, pallets, etc., and are widely used in the packaging and transportation of meat, aquatic products, fruits and vegetables, dairy products, cooked food and other foods
2. The field of pharmaceutical packaging has extremely high requirements for the safety and hygiene of packaging materials. Rubber and plastic packaging has become an important material for pharmaceutical packaging due to its good biocompatibility, non-toxicity and chemical resistance. In pharmaceutical packaging, rubber and plastic materials are used to produce medicine bottles, capsules, syringes, infusion bags, etc. to ensure the safety of medicines during storage and transportation. In addition, rubber and plastic packaging also plays a key role in the packaging of special medicines such as vaccines and blood products.
3. Rubber and plastic packaging is also widely used in the daily chemical industry. Daily chemical products have high requirements for packaging, and need to have moisture-proof, corrosion-resistant, and easy-to-open characteristics. Rubber and plastic packaging materials can meet these requirements and are often used to manufacture packaging for daily chemical products such as shampoo, shower gel, toothpaste, and skin care products. At the same time, plastic packaging also occupies an important position in the packaging of cosmetics, household cleaners and other products, providing consumers with a convenient and safe packaging experience. With the improvement of environmental awareness, the application of rubber and plastic packaging in the daily chemical industry is also constantly developing in the direction of green and environmental protection.
The main types and characteristics of rubber and plastic packaging materials:
1. Rubber and plastic packaging materials mainly include three categories: natural rubber, synthetic rubber and plastic. Natural rubber is made from latex tree sap, has good elasticity and wear resistance, and is widely used in tires, seals and other fields. Synthetic rubber is made by chemical synthesis, such as styrene-butadiene rubber (SBR), nitrile rubber (NBR), etc., which have excellent oil resistance and aging resistance. There are many kinds of plastic packaging materials, the most common ones are polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc., which are widely used in the packaging industry for their lightness, transparency, and easy processing.
2. Natural rubber packaging materials are widely used in the field of food packaging, such as for making cling film, gloves, sealing rings, etc. Taking cling film as an example, natural rubber cling film has good barrier properties and can effectively prevent food from oxidation and deterioration.
3. Among plastic packaging materials, polyethylene (PE) is widely used in food packaging, beverage packaging, daily necessities packaging and other fields due to its excellent chemical resistance, impact resistance and transparency. Taking beverage bottles as an example, beverage bottles made of polyethylene materials have good temperature resistance and can be used in the temperature range of -70C to +120°C. In addition, polypropylene (PP) materials are also widely used in food packaging, household goods and other fields due to their good heat resistance and mechanical strength.
Technological innovation trends of rubber and plastic packaging materials:
1. The technological innovation trends of rubber and plastic packaging materials are mainly focused on improving the environmental performance of materials, enhancing the intelligence and functionality of packaging. In terms of environmental protection, the research and development and application of new materials such as biodegradable plastics and recyclable plastics have become hot topics. For example, the biodegradable polylactic acid (PLA) material developed by a certain company has been applied in the field of food packaging, effectively reducing the pollution of plastic packaging to the environment.
2. Intelligent packaging technology has also been valued in the field of rubber and plastic packaging materials. By embedding smart components such as sensors and chips in rubber and plastic materials, real-time monitoring of packaging and information traceability can be achieved. For example, the smart medicine box launched by a certain company can monitor the storage environment of medicines in real time and ensure the quality of medicines by embedding temperature and humidity sensors and mobile chips in the medicine box.
3. The research and development of functional rubber and plastic packaging materials has also made significant progress. These materials not only have basic packaging functions, but also provide special functions such as antibacterial, moisture-proof, anti-counterfeiting, etc. Taking antibacterial rubber and plastic materials as an example, the antibacterial polyethylene material developed by a certain company can inhibit bacterial growth during the packaging process and effectively extend the shelf life of food. In addition, the application of anti-counterfeiting rubber and plastic packaging materials is also gradually expanding, which helps to combat counterfeit and shoddy products and protect the rights and interests of consumers.
Environmental performance of rubber and plastic packaging materials:
1. The environmental performance of rubber and plastic packaging materials is an important indicator to measure their sustainability. With the improvement of global environmental awareness, the environmental performance of rubber and plastic packaging materials has received more and more attention. At present, a variety of environmentally friendly rubber and plastic materials have appeared on the market, such as biodegradable plastics, recyclable plastics and plant-based plastics. These materials have performed well in reducing the impact on the environment. Biodegradable plastics can decompose in the natural environment and reduce the accumulation of plastic waste.
2. Biodegradable plastics are the key to improving the environmental performance of rubber and plastic packaging materials. This material can be decomposed by microorganisms under certain conditions and converted into harmless carbon dioxide and water. For example, polylactic acid (PLA) is a biodegradable plastic made from renewable resources such as corn starch, which is widely used in food packaging, shopping bags and other fields. According to research, PLA packaging can be completely degraded in the soil in just 120 days, significantly reducing plastic pollution.
3. In addition to biodegradable plastics, recyclable plastics and plant-based plastics are also important ways to improve the environmental performance of rubber and plastic packaging materials. Recyclable plastics can be reprocessed by recycling old plastic products, reducing the demand for virgin plastic resources. Plant-based plastics use renewable plant resources, such as corn starch, vegetable oil, etc., reducing dependence on petroleum resources. The application of these environmentally friendly rubber and plastic materials not only helps to reduce environmental pollution, but also promotes the recycling of resources, which is in line with the concept of sustainable development. With the continuous advancement of technology, the environmental performance of rubber and plastic packaging materials is expected to be further improved in the future.
In short, rubber packaging products are widely used in our daily lives. In addition to its own characteristics, modern science is also constantly innovating and improving in line with development, and working hand in hand with rubber chemical products to move towards a better future.
