Poly bags or more familiar to consumers as plastic bags are the most common type of packaging used in just about every industry for different types of application. Although paper bags are gaining widespread acceptance as eco-friendly means of packaging and carrying items, poly bags are still very popular among many grocery stores and many types of retail outlets. Poly bags are facing huge resistance from green organizations claiming that plastic bags are environmental hazards that often find their way into the water and end up covering coral reefs. However, these poly bags are still gaining control of the packaging industries due to many reasons.
Strong and durable: Poly bags are made from polymers refined from natural gas or oil. Plastics can be made rigid and tough by chemical processes, which makes them hold heavier load while remaining very light. Poly bags are by far durable than most paper bags, which have limited load tolerance and require more of muscle assistance. Moreover, poly bags are less susceptible to rip and tear while handling that there’s a least possibility of your items scattering around.
Convenient: Plastic shopping bags are normally produced with handles for easy carriage while shopping. Obviously, they are far very useful than paper bags when rain comes. Poly bags are very effective packaging material for frozen products because they keep moisture out and preserve food for considerable length of time.
Seal-Flexible: Unlike paper bags, poly bags are flexible to closures. Many innovative ways on how to close them securely have proved to be effective. They can be closed by heat because they easily melt or flipped over by extending one edge. A zip can also be made by pressing a molded groove on one edge and a molded track on the other one. For items that need to be kept fresh or repacked, poly bags can be closed by a slide seal similar to a zipper. Another good idea to seal it is by using a strip or tie wrapped around its neck or by pulling tight a drawstring inserted around the open edge.
Printable: Poly bags are print-friendly. You can basically print anything on them including logos, slogan, trademarks and any marketing strategy signs and symbols. Because poly bags are very flexible, producing them in different colors is uncomplicated.
Sustainable: Poly bags that are totally non biodegradable are notions of the past because since the dawn of sustainable packaging, manufacturers have found means of making them less harmful to the environment. These bags are designed to be reusable even for other purposes. In fact, there are studies that show that plastics bags have less net environmental effect and require less energy to produce. Come to think of it, users have their share of responsibility in optimizing the use of poly bags and should be also held responsible in disposing them properly.
The advantages of poly bags are unmerited to a great extent giving much emphasis to a common misconception of them being a totally environmental danger. However, environmental threat is a by-product of industrial and technological advancement not only by the production of poly bags but also by other manufacturing applications.
