Analysis of Plastic Bottle Cap Technology and Market Development

Because the bottle mouth tolerance is difficult to control to the predetermined range, almost 100% of the hot-filled bottles of the crystalline PET filling and sealing machine are matched with two caps. Since the end of the last century, many companies have tackled key problems and tried to replace them with monolithic covers.

Why

Why are PVC plastic bottles unwelcome?

Compared with plastic bottles of other materials, it is an indisputable fact that the market share of PVC plastic bottles has become lower and lower in recent years. Compared with plastic bottles of other materials, PVC plastic bottles have lower packaging costs and have a higher market share for a period of time.

How

How to buy plastic bottles

First. The development history of plastic bottles:In the 1980s, as my country continued to introduce advanced plastic bottle production lines from abroad, the prelude to "plastic" replacing "glass" was opened. Since then, plastic bottles have been widely used in the packaging field. Plastic bottles are mainly made of non-toxic high-molecular polymers such as high-density polyethylene (HDPE), polyester (PET), polypropylene (PP), polycarbonate (PC) as the main raw materials, using advanced plastic molding technology And equipment to produce various plastic bottles, mainly containing various types of capsules, granules, tablets, powders, capsules, oral liquids and other solids and liquids. Second, the use of plastic bottles: At present, most of the medicines, nutrition and health products, various foods and beverages on the domestic market are packaged in plastic bottles. You can find products packaged in plastic bottles everywhere you go to pharmacies or supermarkets. Medicines and nutrition and health products mainly use polyester bottles (PET bottles) and high-density polyethylene bottles (HDPE bottles), beverages mainly use polyester bottles (PET), and daily necessities such as shampoos and shower gels use high-density polyethylene There are more bottles (HDPE bottles). The biggest feature of plastic bottles is that they are light, not fragile, clean, and beautiful. Some of its technical indicators and a large amount of data show that its chemical resistance, water vapor permeability, and sealing performance are excellent. It is completely can play a role in safety shielding and protection of the products installed during the validity period. Third, the principle of choosing plastic bottles: 1. Regardless of what raw material is selected, plastic bottles must first meet the requirements of non-toxicity and no peculiar smell. Due to the wide variety of main raw materials available, it is necessary to select the comprehensive properties of the raw materials. Generally, high-density poly Ethylene and polypropylene bottles. If transparency is required, polyester bottles (PET bottles) can be used. If higher barrier performance, light blocking and opacity are required, brown PET bottles are used. Liquid dosage medicines generally use polypropylene bottles or polyester bottles as the main raw materials. . At present, the domestic nutrition and health products and food packaging bottles are mainly made of PET or HPDE, and the caps are made of PP. 2. The airtightness and water vapor permeability of the bottle body and cap. Tightness and water vapor permeability are two important technical indicators of plastic bottles, and they have an important impact on the stability of the packaged product. 3. Quality standards for plastic bottles. The pros and cons of product quality can be analyzed and judged from the product quality standards of the manufacturer. 4. Quality assurance system. Auditing suppliers has become an essential part of purchasing plastic bottles. Through the audit, it is possible to make a comprehensive and correct assessment of the production plant's software and hardware facilities, technical equipment, and comprehensive quality level. 5. Recycled materials must not be used for packaging medicines, nutraceuticals, food and beverages. The "Measures for the Hygienic Management of Plastic Products and Raw Materials for Food" promulgated by the Ministry of Health has clear provisions: "Recycled plastics shall not be used for processing plastic utensils, containers, and food packaging materials." Fourth, the status quo of plastic bottles The Ministry of Health’s "Food-Use Plastic Products and Raw Materials Hygiene Management Measures" clearly stipulates: "Where plastic food utensils, containers, and food packaging materials are processed, recycled plastics shall not be used." Recycled waste plastics can be processed into other products. At present, many businesses, driven by their interests, tend to choose low-cost recycled materials to make products, which is indeed worrying. If you find impurities on the bottle during use, and the transparency of the transparent bottle is low, you should be more vigilant and polish your eyes.

Old plastic bottles "Nirvana rebirth", garbage classification to create a circular economy

Garbage is just a precious resource that is misplaced. So, how does rubbish turn waste into treasure? Domestic waste sorting, domestic waste sorting and disposal pilot base. Many recyclable garbage arrives at the domestic garbage sorting center after leaving the trash bin. Fine sorting and packing of collected recyclable garbage, disassembly and decomposition of bulky garbage, and temporary storage of hazardous garbage... In the waste plastic workshop of Hefei Municipal Solid Waste Sorting Center, a dozen workers finely sort various plastic bottles The monthly processing capacity is more than 300 tons. PE and PET are actually polyethylene and polyester. As two kinds of widely used plastics, they can be reprocessed into chemical fibers. Among them, polyester is a chemical fiber product processed by polyester, which can be used to make clothes or be used as clothing fillers. After    sorting, PET polyester plastic bottles will be packaged into bundles for further processing. Anhui Win-Win Group Southeast Renewable Resources Co., Ltd., located in Tongling City, has a production line that can "make a facelift" for such plastic bottles. After the bundles of plastic bottles are unpacked, they enter the dismantling equipment. The dismantled bottles will be shattered and sent to the cleaning and separation tank. The plastic sheets after winnowing become the raw materials of the chemical fiber factory, and they will be transported to the next station. Here, the drying process must be carried out first. Subsequently, these filaments with a diameter of a few micrometers, after winding, bundling, drawing, crimping, heat setting, cutting and other steps, become long chemical fiber products. In this way, the plastic bottle has completed the "Nirvana rebirth". ". It takes about 5 bottles to make a T-shirt, and 40-60 plastic bottles to make a mattress. At present, my country's annual consumption of plastic bottles exceeds 5 million tons, ranking first in the world, while recycling 10,000 tons of beverage bottles can save 60,000 tons of oil. The recycling of plastic bottles contains huge economic value. All material forms can be turned into resources as long as they are reasonably and appropriately used. At present, we are vigorously building a "resource-saving society and an environment-friendly society". The establishment of a "two-oriented" society requires the development of a circular economy, and the development of a circular economy requires the establishment of a good garbage classification system in the whole society
