Many people still know nothing about how to tell good plastic bags from bad ones. Quite a number of them regard plastic bags as trivial items, thinking that there is no difference between different options. Besides, these products themselves are not expensive—they can be bought for just a few cents—so people don’t really care even if they end up with low-quality ones. However, plastic bag manufacturers point out that this idea is completely wrong. For large-scale sellers who purchase plastic bags in bulk, a batch of defective products will lead to far greater losses than just one or two substandard items. Here, Sayru Technology, a professional manufacturer of eco-friendly plastic bags, deems it necessary to explain the methods for distinguishing high-quality plastic bags from inferior ones.
Sayru Technology states that high-quality plastic bags on the market typically excel in three key aspects: alkali resistance, tensile strength, and crack resistance. Among these, alkali resistance is the core attribute. The reason is that if a plastic bag has high tensile strength but poor alkali resistance, its overall durability will be compromised during use, rendering its crack resistance ineffective. The alkali resistance of a plastic bag mainly depends on the raw materials used in its production and the additives incorporated in the manufacturing process.
Sayru Technology also warns that the use of low-quality plastic bags will bring about a series of problems. Inferior plastic bags are likely made from recycled secondary packaging materials, and toxic chemicals may be added during the production process. Such plastic bags have the potential to emit substances harmful to human health. Unfortunately, it is difficult for consumers to identify whether a plastic bag is made from recycled materials just by visual inspection. Fortunately, market supervision over low-quality plastic bag products has been strengthened in recent years. Therefore, consumers should pay close attention to the production processes and raw materials of plastic bags to ensure greater peace of mind when purchasing and using them.
The application of biodegradable materials by Shenzhen Sayru Technology Co., Ltd. has transformed the properties of traditional plastics. Products made from these materials can degrade under sunlight and are easily decomposed by the environment when disposed of. The company’s biodegradable masterbatches can also improve the combustion performance of products, reducing the emission of harmful gases during incineration. As a manufacturer specializing in the R&D, production, and sales of plastic bag products, Sayru Technology boasts rich industry experience and has obtained a number of invention patents over the past 8 years.
Sayru Technology has independently developed a range of high-tech eco-friendly products, including biodegradable film products, biodegradable materials, straw composite materials, biodegradable plastic bags, starch-based biodegradable plastic bags, and plant fiber-based biodegradable plastic bags, along with their derivative product lines. With multiple patents granted for these innovations, the company has become a production base of the Technological Innovation Strategic Alliance for the Biodegradable Industry.
