P R ODUC T SThe bas ic material used to manufacture plastic

woven bags is polypropylene (P P ), a thermoplastic

synthetic polymer of propylene that has relatively

high strength. P ure polypropylene is white while

the color of the bags can be eas ily changed by

adding color to raw P P material. The circular

loom is adjusted to weave a plastic cloth tube with

a required diameter. C utting and sewing

operations form the final product.

B as ic woven P P bags can be used to hold

granular material but they are not waterproof. To

keep the moisture from getting into the packages ,

a thin plastic coating can be applied on the woven

cloth. B ags usually come with customized prints .

Multicolor printers can directly print lettering and

s imple images on the woven fabric . However, to

make the beautiful full color packages such as

required by consumer-oriented products , the

image has to be preprinted on a B OP P film

employing full color plastic printer. The thin film is

then laminated on the woven P P bags .

P olypropylene woven packaging has been used

widely in many industries due to its s trength and

versatility. Most often they are used in the

packaging of fertilizer, grain, flour, cement, pet

food, sand, and chemicals , etc.

Multiple s teps are involved in the manufacturing of

polypropylene woven bags . S ince polypropylene is a

thermoplastic polymer, the firs t s tep is to melt the

granular polypropylene and pull it into flat threads .

During this process color pigment can be added to

make bags with other colors than white. High speed

circular looms weave the threads to form a

continuous tube of woven plastic cloth. The diameter

of the tube is determined by the final dimension of

the bags . The plastic cloth tube will then be cut to

the required length and the end sewn to form a bag. To

make it moisture proof, a coating layer can be applied on

the woven plastic , or some customers prefer to have an

inner bag made of thin film. The bags can be multicolor

printed or have the full color print on them. Full color is

achieved by preprinting plastic film with full color plastic

printer, and laminating the film on the bag.

Basic woven PP bags can be used to hold

granular material but they are not waterproof. To

keep the moisture from getting into the packages,

a thin plastic coating can be applied on the woven

cloth. Bags usually come with customized prints.

Multicolor printers can directly print lettering and

simple images on the woven fabric. However, to

make the beautiful full color packages such as

required by consumer-oriented products, the

image has to be preprinted on a BOPP film

employing full color plastic printer. The thin film is

then laminated on the woven PP bags.

Polypropylene woven packaging has been used

widely in many industries due to its strength and

versatility. Most often they can been seen in the

packaging of fertilizer, grain, flour, cement, pet
