Poly bags are one of the most popular forms of flexible packaging. They guard against airborne contaminants like dust, dirt, debris, and bacteria. In addition, they protect products from electrostatic electricity, which is why many packaging companies use poly bags to package electronics like iphones, smart phones, ipods, and other delicate items.

Material

Poly bags are made from PolyEthylene, man-made plastic capsules of resin commonly found in plastic containers, food packaging, and toys. The plastic contains a repeating molecular structure that dictates its density, or strength. Each pattern is called a polymer. If the polymers are widely spaced apart, the plastic has a low density and will form a flimsier poly bag. Likewise, if the polymers are more tightly spaced, the poly bag will have a higher density.

Uses for Poly Bags

The purposes of poly bags vary depending on the density. High-density poly bags protect machinery, furniture, weapons, and auto parts. Packaging companies use both types for dry food such as nuts, candy, and powdered mixes; office supplies like paper clips, erasers, and thumbtacks; chemicals like rat poison and fertilizer; large objects like firewood, ice, and vacuum bags; and even larger objects like trash cans and furniture.

History

The material for the first poly bags came about in 1862 when Alexander Parkes presented it in London during the Great International Exhibition. Parkes manipulated a natural form of cellulose by first heating it and then forcing it into a permanent shape as it cooled. The material for plastic is composed mostly of natural gas and petroleum. The term “poly bags” didn’t become popular till a decade later when petroleum became more common.

Why are our Barrier Bags so Popular?

When our customers consider barrier packaging, we prefer to speak with them first to recommend the best material for each project. We take into account several factors that will determine material selection and construction of each bag or pouch. Some of these factors include the product, the end use, the environment it may encounter, dimensions, storage conditions, intended duration of storage, and your internal specification. Your satisfaction and project success are our #1 concern!

Thinking of going green with your barrier bags? Are you looking to reduce your carbon footprint and find more sustainable options? Barrier bags help reduce the production of greenhouse gases.
