Shopping bags, as the name implies, are used for shopping. At present, the shopping bags available in the market mainly include plastic shopping bags, non-woven shopping bags, paper shopping bags, cotton and hemp shopping bags and so on. Plastic shopping bag is a kind of packaging material made of polyolefin and other materials. At present, the main polyolefins used are polyethylene (PE), commonly known as soft rubber. The main products include low-density polyethylene or high-pressure polyethylene (LDPE), high-density polyethylene or low-pressure polyethylene (HDPE), linear low-density polyethylene (LLDPE) and metallocene polyethylene (mLLDPE). 


In order to reduce the cost, most enterprises in recent years have added about 30% calcium carbonate to make filled plastic shopping bags. Such plastic shopping bags do not emit toxic gases when they are burned in garbage sites. Ordinary plastic shopping bags use polyolefin and filler as raw materials, while this kind of plastic shopping bags do not have degradation performance, which will not be degraded when abandoned in the field. This kind of plastic shopping bag has excellent recyclability and can be recycled for many times. Faced with so many shopping bags, let's distinguish between cotton bags and canvas bags in terms of raw materials.


Different weaving processes

The warp and weft yarns of cotton cloth are mostly single strands, which are made of finer cotton yarn. So the stitches of the reusable cotton bag are more detailed. In most cases, cotton and linen are woven in both plain and twill patterns.


The raw material of canvas bag is composed of two or more strands, which leads to the rough appearance of waxed canvas bags. In addition, plain weave is usually used for canvas, while twill weaving is rarely used.



Different characteristics

Cotton and flax have high strength, good wrinkle resistance and tensile property, which lead to better heat resistance and acid resistance of cotton produce bags. In addition, it is resistant to dilute alkali at room temperature and has good affinity to dye. Furthermore, Cotton linen cloth has the characteristics of softness, moisture absorption, air permeability and warmth retention.


Canvas is a kind of thick cotton fabric or hemp fabric. Most of the yarn specifications are thicker than ordinary cotton yarn. The fabric is firm and folding resistant, which has good waterproof performance. Its characteristics are very strong and durable.



Different uses

The cotton and linen raw materials of cotton mesh produce bags can be used as textile raw materials to weave various cool linen and summer cloth. It can also be blended with cotton, wool, silk or chemical fibers. Jute and hibiscus hemp are suitable for spinning ropes and packing sacks. Cotton and hemp can also be used to make ropes.


The raw material of blank canvas tote bags can be used for automobile transportation, covering of open warehouse and outdoor tent. Canvas is used to make labor protection clothing and articles. After dyeing or printing, it can also be used as shoe material, bag fabric, handbag, backpack, tablecloth, and so on. In addition, there are rubber canvas, fireproof and radiation shielding canvas, and paper machine canvas.
