Multi-layer Composite Valve Bag For Cement And Construction Materials

Manufacturing process

An increasing number of prominent manufacturers are opting for plastic woven composite kraft paper bags as their preferred bulk packaging solution, instead of multi-layer paper bags.

These bags boast an aesthetically pleasing and robust design, maintaining their integrity during storage and transit. Moreover, the imagery printed on the coated polyester fabric is striking and vivid, with BOPP bags capable of accommodating up to 8 colors, which significantly enhances their visual appeal on retail shelves.

The Ad*Star® Bag, patented globally by Starlinger, is crafted with care exclusively on Starlinger machines. We are proud to say that we have been the leading Ad*Star Bag manufacturer since 2009 right here in China

More Practical and Cost-effective Option

Numerous companies and their clientele value the classic look of paper bags; however, the application of laminated PP woven fabric provides a viable alternative. By matching the outer coating color to that of kraft paper, the resultant bags not only become more utilitarian but are also capable of securely transporting a variety of items without risk of tearing, thereby substantially reducing product loss.

Protect Your Content Safety From All Angles

The composite bags in question are impervious to water, a stark contrast to the vulnerability of paper bags to moisture, which can easily cause them to rupture. The paper-lined PP bag demonstrates enhanced resilience to adverse weather conditions compared to its conventional paper counterpart, ensuring the bag's integrity and the safety of its contents even in inclement weather such as rain or sleet.

In addition to being waterproof, these bags are also impervious to chemicals and most acids, making PP an exemplary material for crafting bags in diverse dimensions. Their versatility allows for usage across a broad spectrum of products without compromising the integrity of the goods. The PP lined paper bag is not only durable but also visually striking, presenting enhanced prospects for packaging and promotional endeavors.

Applications

These bags are neatly folded at the edges and heat sealed at the top and the bottom. The top position of the bag can be equipped with a valve structure for hassle-free automatic filling, making these bags ideally suitable for streamlined packaging needs in industries like cement, animal feed, chemicals, and fertilizers.
