ASA Corporation Co., Ltd. works tirelessly to improve and develop both design and technology to create a better product and service to meet our customers' packaging. We also have implemented our cutting-edge packaging screening which results in matching the best suited bag to our customers, giving the them the best option for their needs and the best price

We provide the whole-in-one services to make the process as easy as possible for our customers, from the initial bag concept to delivery and after-sales service.

We use only the best polypropylene and polyethylene pellets to extrude our tape in top-of-the-line extruders. This gives us the best-quality tape from which to weave our cloth. We can make the tapes in a variety of widths and weights.

Weaving: Our many high-end looms produce the wide variety of polypropylene and polyethylene cloth we need to make our bags.

Lamination: Using one of our six lamination machines, we can coat the woven cloth for a simple bag, or we can laminate it with up to six layers with PP film, PE film, MPET, or paper.

Conversion: The laminated cloth is converted into bags on one of our 10 converters or two AD*Star machines. Basic flexo printing is done in this department as well.

Sewing: We have both automatic sewing machines and a large number of highly skilled seamstresses who can close bags, attach handles, or make shopping and tote bags. They also serve as one more line of quality control.

Gravure Printing: Our high-end printing is done on roto-gravure 8-color presses. This process rivals that of any other type of printing used in the packaging industry. All our cylinders are diamond-stylus engraved ensuring the absolute highest-quality print job.

Logistics department: Our logistics system is accepted by the international standards. We can guarantee the safety and punctuality for all deliveries from the factory to our customers.

Storage department: We employ a systematic process for storage of all materials as well as finished jobs. Each customer's orders are stored separately to ensure product integrity as well as easy shipping. If the bags are being stored for a customer's future use, we maintain environmental conditions to ensure each bag is as new when delivered

We employ a multi-step QC process where every member of our staff becomes part of the solution. From the extrusion to packing, each production step has multiple QC actions which endure that the final product meets our customers' expectations. Some tests are quantitative such as tensile strength and drop testing. Some are qualitative where we rely on our staff to see and reject bags which don's meet our standards. Using accepted ISO standards, we screen, test, reject, and analyze to make sure our products met the needs of our customers. If problems are found, the subject bags are rejected, and the root cause of the problem identified and fixed.


Simply put, woven polypropylene is the best material for making bags, especially bags which will contain large quantities of granular or small-sized products such as pet food, rice, seeds, charcoal, kitty litter, grain, cement, fertilizer, dry chemicals, powdered minerals such as gypsum, potatoes, and other similar products.

Woven polypropylene bags offer many advantages over paper and jute.:

Lighter weight
Much greater bursting strength
Better pest resistance
Resistance to tearing
Reusable
Can be air permeable and moisture, pollutants, bacteria, mildew, and oil resistant
Properties do not degrade if wet
Less expensive
For these reasons, more and more companies are packing their products in polypropylene bag. This has been especially true in the B2B arena where appearances are not as important as cost and performance.
