Is Polyethylene Toxic?

"Polyethylene itself is non-toxic. Polyethylene is mainly divided into high-density polyethylene, low-density polyethylene and linear low-density polyethylene. The surface of polyethylene is dull, milky white waxy granular, corrosion-resistant , the water absorption is relatively small, and the electrical insulation is relatively high. It is mainly divided into two production processes: high-pressure tube method and kettle type. It is mainly used for agricultural film and industrial packaging film products."

Color-printed packaging bags can be used for both transportation packaging and sales packaging, with large scale, wide application, and easy processing. Compared with other packaging materials, color-printed packaging bags have lower raw materials and production costs. Disadvantages of flexible packaging bags Mainly based on custom processing, no stock, only accept orders, not suitable for customers with tight delivery time. There is a certain MOQ, which is not suitable for customers with small quantities. Manufacturers can only win customers by providing more one-stop value-added services, and help customers understand the market from the customer's standpoint. Through the company's pre-press technology design strength, we can help customers choose the best product design scheme, help customers improve product quality, save costs, and maximize customer benefits, so as to become your regular customer.

Talking about the misunderstanding of packaging use

Since the birth of plastic packaging bags, it has been loved by people for its lightness, cheapness and high strength. People have become accustomed to using plastic bags to pack things. There are many types of plastic packaging bags on the market, but there are countless types in terms of color, so what kind of good ones? Will we really choose plastic packaging bags? Although we can use plastic packaging bags almost every day, we often go into misunderstandings about the choice of plastic packaging bags. (1) The thicker and stronger the plastic bag, the better. We often see all kinds of plastic packaging bags in our lives, so a strong packaging bag must be good. In fact, this is not the case. There are strict standards for plastic packaging bags, especially plastic bags used for food packaging. They must be produced by regular manufacturers and have qualified products approved by relevant departments. The quality of these plastic bags will be Guaranteed. Plastic bags for food must be marked with the words "for food". Look into the light to see if the plastic is clean. Qualified plastic bags are clean and free of impurities, while inferior plastic bags will see dirty spots and impurities. The thickness of one side of the plastic bag must be more than 0.025mm. If it cannot reach this thickness, the state prohibits production and use. (2) The plastic packaging is colorful, how beautiful it is to choose colorful packaging. Although there are many kinds of colors for plastic packaging bags, we must be careful when choosing them. If the plastic packaging used for food items is used, only in terms of color, we must choose simple colors, so that at least it has less additives. Many dark-colored plastic packaging bags are often produced from recycled waste materials, and these plastic bags cannot directly contact food. (3) Reuse of plastic bags. Many families have the habit of storing waste plastic bags. In fact, it is okay to store them as long as they pay attention to cleanliness and the use of waste plastic bags, but do not use waste plastic bags for food and skin. It will be harmful to our health. cause chronic damage.
