Woven Polypropylene Non-coated Bags
This is our most basic bag. Circularly woven, this is a seamless bag which offers strength as well as permeability. Graphics are printed using a four-color flexo process. This is a cost-effective bag where strength is needed, but not high-end graphics. This bag is typically used for commercial grains, animal feed, fertilizer, textiles, and other such products.
Circularly-woven Polypropylene Coated Bags
This bag is constructed in the same manner as the non-coated bag, except that the woven polypropylene scrim is coated with a layer of polypropylene extrudate. This provides a better moisture and air barrier, thereby better protecting the products being packaged. Ike the non-coated bag, this bag can be printed upon on both sides. It is suited for animal feed, seeds, plastic resins.
Woven Polypropylene Sealed and Coated Bags
This bag is a bag coated using the same process as for the circularly-woven coated bag. However, the woven scrim is slit in the weaving process, and it is coated and printed flat as one sheet of scrim. When the bag is formed, it is formed with a backseam of between 3 and 6 inches. This is a very durable, cost-effective bag, suitable for products such as fertilizer, lime, calcium, plastic resins, and similar products.
Woven Polypropylene Kraft Paper-laminated Bags
This bag is made by laminating kraft paper to the woven polypropylene scrim. The paper is normally printed using a four-color flexo process. More suitable for commercial packaging, this bag is generally used for products such as plastic resins, chemicals, and minerals.
Woven Polypropylene White Fine Paper-laminated Bags
This bag is similar to the previous bag in construction; however, by using white paper instead of brown kraft, the paper can be printed using eight-color roto-gravure printing. This makes this bag more suitable for products which need a good shelf-appeal such as dog food, rice, animal feeds, and home and garden products.
Woven Polyethylene Metalized Polyethylene-laminated bags
Using a woven polyethylene scrim, the inside or outside of the bag is laminated with a metalized polyethylene (MPET) film. This gives the bag the appearance of a metal foil layer. While the MPET does give the bag slightly better air permeability and light protection, the primary difference in this bag is the customer perception of product protection. Typical uses of this bag would be to package pet food, rice, flour, and other consumables.
Woven Polypropylene Film-laminated Bags
This is our standard three-layer bag. The inner woven polypropylene scrim is coated with a polypropylene extrudate which is used to laminate a polypropylene film to the outside of the bag. The outer film layer is reverse printed before the lamination process, so when the bag is constructed, the print is actually protected from wear by the thickness of the film. By using high-quality eight-color roto-gravure presses, the print is of the highest quality available, whether printing real images such as dogs or with simple graphics. And by using reverse printing, this print will not wear off so not only does it look great with, items such as bar codes can always be read. This bag is suitable for retail products where the quality of the product needs to be conveyed to the buying customer. Current users of this bag include pet food, rice, seed, garden products, charcoal, wood chip, animal feed, and bird seed companies.
