Dongguan woven bags the most important feature is that it has plastic products do not have the environmental performance, which is far below the natural degradation of plastic time, therefore, the use of non-woven fabrics made of non-woven bags are also recognized as the most affordable shopping bag.

Non-woven shopping bag which classification process

Non-woven shopping bag according to the production process can be divided into:

1, spunlace: a high-pressure water jet to a fine one or more layers of fiber web, the fibers tangled with each other, whereby the fiber network to have a certain strength and reinforcement.

2, heat sealing woven bags: is added to the web or fibrous reinforcement material fused powder, fiber network and then cooled after heating and melting the reinforcement into cloth.

3, pulp airlaid non-woven bags: can be called airlaid dry papermaking nonwoven fabric. It is the use of airlaid technology wood pulp fiberboard opener into a single fiber state, and then use the airflow method on the fiber aggregation into a network of screens, fiber network and then reinforcement into cloth.

4, wet non-woven bags: is placed in an aqueous medium fiber material opening into a single fiber, while the mixing of different fiber materials, made of pulp fiber suspensions, suspended pulp conveyor into a network of institutions to the fibers in the wet state By then into a network reinforcement into cloth.

5, spunbonded nonwoven bags: after the polymers have been extruded, stretched to form a continuous filament, the filament laying into a web, the web and then through the self-adhesive, thermal bonding, chemical bonding or mechanical reinforcement method, the fiber network into a nonwoven fabric.

6, meltblown nonwoven bags: its process: the polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- into the network --- reinforcement into cloth.

7, acupuncture: a dry non-woven, non-woven fabric is the use of acupuncture needles puncture role fluffy fiber mesh reinforcement into cloth.

8, stitch: is a dry nonwoven fabric, stitch using warp coil structure of the fiber network, yarn layer, non-woven material (such as plastic sheets, plastic thin metal foils, etc.) or a combination thereof body reinforcement, to produce non-woven fabrics.
