The PP nonwoven bag is a green product made from nonwoven fabric (its raw material) by a nonwoven bag machine, without any auxiliary materials and solvents. It is durable, fashionable, breathable, reusable, washable, and is open to advertisements and trademarks by screen printing. For companies, it is a good option for advertising and preparing gifts. There are two types of equipment to make nonwoven bags: automatic nonwoven bag machine and ultrasonic lace machine (semi-automatic nonwoven bag machine). With a high degree of automation and efficiency, and automatic nonwoven bag machine is mainly adapted to the production of manufacture flat bags, side-gusseted bags, bottom-gusseted bags, etc. Thus, it is widely used by large nonwoven bag manufacturers with fixed orders from customers.
Loading (nonwoven fabric coiled material) → folding → ultrasonic adhesion → cutting → bag making (punching) → waste recycling → counting → stacking.
The process can be fully automatic, requiring only 1 or 2 people to operate, and the production speed and product size can be adjusted within a certain range. The multi-functional automatic nonwoven bag machine is equipped with touch screens and industrial control devices including stepping fixed-length devices, photoelectric tracking devices (accurate and stable), automatic counting devices (counting alarm can be set), and automatic punching devices. Meanwhile, for energy saving and environmental protection, the machine can recycle residual materials during the production and automatically collect the waste, which is helpful for secondary use, reduces labor intensity, and increases working efficiency.
It is lightweight. The fluffy and tactile bag is made mainly from PP resin, with a specific gravity of only 0.9, three-fifths of cotton.
It is soft. Composed of fine fibers (2-3D) through thermal adhesion, finished products are moderately soft and comfortable.
It is water repellent and breathable. PP chips are non-absorbent and contain no water, with finished products being water repellent. Consisting of 100% fiber, the bag is porous, breathable, and easy to stay dry and to wash.
It is non-toxic and non-irritant. Produced with FDA food-grade raw materials, the product does not contain other chemical ingredients or peculiar smell and is reliable, non-toxic, and skin-friendly.
It has antibacterial and anti-chemical agents. As a chemically inactive substance, polypropylene will not be eaten by worms, and can prevent attacks from bacteria and insects in the liquid; it is invulnerable to bacteria and alkali corrosion, which keeps the strength of finished products from being affected by the attacks.
It is antibacterial. The product is water repellent and can prevent attacks from bacteria and insects in the liquid. It will also not be moldy or eaten by worms.
It has good physical properties. Made from PP spinning net through thermal adhesion, the bag has better strength than ordinary staple fiber products. The non-directional strength is close in the vertical and horizontal directions.
In terms of environmental protection, the raw material of most nonwoven fabrics and plastic bags are polypropylene and polyethylene respectively. In spite of similar names, the two substances are quite different in chemical structure. With a very stable chemical structure, polyethylene is hardly degradable. Thus, it takes plastic bags 300 years to decompose completely. Polypropylene’s molecular chains can be easily broken owing to an unstable chemical structure, which can bring about effective degradation whose products will enter the next environmental cycle non-toxically. A nonwoven shopping bag can be decomposed completely in 90 days. Moreover, it can be reused more than 10 times, and the environmental pollution after disposal is only 10% of the plastic bag.
