When looking for packaging solutions for your products, could sideweld poly bags be the right fit for your business? 

Sideweld poly bags are rigorously tested to make sure that the seam is as strong as the base material. They come in a variety of colors, sizes, and thicknesses that can be customized to your unique application. These bags are a common choice for packaging frozen food, ice, plastic parts with sharp edges, and more. 

Let’s discuss the qualities of sideweld poly bags, what they’re used for, and their specifications. 

How Sideweld Poly Bags Are Made

Sideweld poly bags are made using a centerfolded film that is welded and cut, producing seals on the side of the bag. The bags are then tested to ensure that the seal is at least as strong as the base material. This makes sure the bags will not tear along the seal and are resistant to scratches, moisture, and rust. 

What Are Sideweld Bags Used For? 

Sideweld bags are manufactured from a variety of different materials, making them a versatile solution for a variety of applications. They are most commonly used for bread, meat/poultry, box liners, food bags, and parts bags.

The parts bags can be utilized by a wide range of industries, storing medical, plastic, metal, and industrial parts. The durability of sideweld bags makes them a great choice when scratch-protection, UV ray protection, and rust protection is required. They’re also a moisture-resistant option for powders, granules, frozen foods, and ice. 

Unique Features of Sideweld Bags

What makes sideweld poly bags unique is the strength of their seal. Tested using the highest quality standards to ensure they do not split, the seal is at least as strong as the base material. These bags keep items like frozen food, ice, and metal parts safe in their packaging. Whereas the seam of other packaging materials is typically a weak point, sideweld bags maintain their strength at the seam. Along with UV protection, moisture resistance, and scratch protection, they’re a secure solution that services a variety of applications across many industries.

Sideweld poly bags can be manufactured in a wide range of sizes to fit your application. The smallest size is 2” x 3”, ranging up to the largest size of 52” x 52”. Available thicknesses include .75-4mil. If you’re not sure which size bag you need, check out our guide on how to measure poly bags
