There are many packaging products made from different materials on the market, and plastic is a very important component.   Here are the advantages of PET wide-mouth bottles compared to glass wide-mouth bottles: In terms of safety ​Strong impact resistance: PET materials possess excellent toughness and impact resistance. In contrast to glass wide-mouth bottles that are highly fragile, PET wide-mouth bottles are less likely to break when subjected to external impacts such as collisions or drops. This significantly enhances the safety of protecting the items stored inside and reduces the risk of damage. This feature is particularly beneficial in households with children or the elderly, as it effectively minimizes the risk of personal injury caused by shattered glass. ​No sharp fragments: Even in the rare event of damage to a PET wide-mouth bottle, it won't produce sharp glass shards like a broken glass bottle. This eliminates the danger of cuts and other injuries caused by sharp fragments flying around. In terms of convenience ​Lightweight: PET has a relatively low density, which means that PET wide-mouth bottles are much lighter than glass wide-mouth bottles of the same size. This makes them more convenient to carry during daily use, whether it's for carrying cosmetics, food, or other items when going out. In industrial transportation, the reduced weight also means lower labor intensity during handling and can significantly reduce logistics costs. Additionally, their light weight makes them more suitable for e-commerce and other scenarios that involve frequent transportation and handling. ​Less prone to breakage during transportation: Thanks to their light weight and good impact resistance, PET wide-mouth bottles are less likely to be damaged during transportation. This not only reduces product loss during transit but also improves transportation efficiency and lowers overall transportation costs. Moreover, their durability makes them more appropriate for products that require personalized packaging, such as food and daily necessities. In contrast, glass wide-mouth bottles have relatively fixed shapes and styles, and manufacturing bottles with complex shapes is often more expensive. ​Diverse shapes: PET materials can be easily molded into various complex shapes and designs through injection molding and other processes. This enables them to meet the diverse and personalized packaging needs of different products, making them more appealing to consumers. In comparison, glass wide-mouth bottles have more limited shape options, and creating bottles with unique or intricate designs is often more costly and technically challenging. Other aspects ​Low cost: PET raw materials are abundant and readily available, and the production process is relatively mature. As a result, the manufacturing cost of PET wide-mouth bottles is lower than that of glass wide-mouth bottles. This cost advantage gives PET wide-mouth bottles a competitive edge in the market. For products with cost-sensitive markets, such as food and daily necessities, using PET wide-mouth bottles can effectively reduce packaging costs without sacrificing quality. ​Good chemical stability: PET exhibits good resistance to a wide range of chemicals and does not react chemically with most foods, cosmetics, and drugs. This ensures the quality and safety of the items stored inside the bottles. However, it's important to note that PET materials may not be suitable for long-term storage of oily substances or liquids with high alcohol content, as there may be a certain degree of leaching in such cases. But under normal use conditions, their chemical stability is sufficient to meet the packaging requirements of most products.  

Blow molding produces hollow containers like jars and cans by inflating heated plastic into molds using compressed air. Injection blow molding ensures precision for plastic jars and cans (e.g., jars for nuts, candies, dry fruits, food packaging, peanut butter, spice jars, and cans for drinks, food, sauce). This method offers design flexibility, minimal material waste, and high-speed automation, ideal for mass-producing jars/cans for food (peanut butter jars, beverage cans). Its lightweight yet durable structure, chemical resistance, and ability to withstand pressure make it a sustainable alternative to glass. Advancements focus on recycled materials and ergonomic designs, enhancing eco-friendliness and usability in jar/can production.
