Packaging bags refer to bags used to pack various supplies, which are widely used in daily life and industrial production. There are various packaging bags on the market, so today we will introduce a few different packaging bags.
1. Plastic shopping bag
Plastic shopping bags are packaging materials made of polyolefin as the main raw material and appropriate addition of other substances. The polyolefins currently used are mainly polyethylene (PE), and the main products include LDPE, HDPE, LLDPE and mLLDPE. The current plastic shopping bags are divided into the following three categories.
a. Ordinary plastic shopping bag
This plastic bag uses polyolefin and fillers as raw materials. This kind of plastic shopping bag does not have degradability, and it will not be degraded even if it is abandoned in the field. Such plastic shopping bags have excellent recyclability and can be recycled and reused many times. But the pollution to the environment is relatively large.
b. Starch-based plastic shopping bag
This type of shopping bag uses modified starch as the main raw material, and a small amount of other degradable materials is appropriately added to improve its performance. The plastic shopping bag can be naturally degraded after being discarded in the wild. However, because starch-based plastic shopping bags use starch as the main raw material, and starch comes from grain, so the development of starch-based plastic shopping bags also has certain restrictions.
c. Degradable plastic shopping bag
This type of shopping bag is produced from completely degradable plastics and has complete degradability. This kind of plastic bag can be completely degraded into small molecule microorganisms when thrown away in the wild, without any environmental pollution. At present, this kind of plastic shopping bag is promoted all over the world.
2. Paper shopping bag
As the name suggests, paper shopping bag is made of paper materials. Paper shopping bag is widely used in today's society. Paper shopping bag is used for packaging in most industries, such as food, clothing, and electronic products. Paper shopping bag has become everyone's favorite packaging products because of its convenience and practicality and simple appearance.
3. Non-woven shopping bag
Non-woven shopping bag is an environmentally friendly product. It has the characteristics of toughness and durability, beautiful appearance, good air permeability, reusable, washable, silk-screen advertising, marking, and long service life. It is suitable for any company and any industry as advertising and gifts. Consumers get an exquisite non-woven bag while shopping, and businesses also get invisible advertising, which makes non-woven fabrics more and more popular in the market. The non-woven bag is made of non-woven fabric. The material can be naturally decomposed when placed outdoors for 90 days. It is non-toxic, odorless, and has no leftover substances when it burns, so it does not pollute the environment.
4. Cotton linen shopping bag
The strength of cotton and linen shopping bags is better than that of paper bags. The advantage of the cotton and linen shopping bag is that it can be recycled, and it can be used multiple times after being cleaned, which can reduce the waste of resources.
