The History and Manufacturing Process of Poly Bags
By definition, poly bags are created with the most popular plastic form called polyethylene. They are used to carry various sealed goods. Many might identify poly bags because they are characterized by their simple and sleek design, smooth curves, and small frames. However, one might find a custom poly bag used to store and ship a few items such as comic books, chemicals, and even food.
A Little History
The use of plastic and creation of plastic bags dates back in the 1950s. Back then, the plastic bags were used for industrial purposes only, specifically for composite construction. It was not until Sten Gustaf Thulin started creating a plastic shopping bag that would then become the forefather of the plastic bags we use today sometime in the 1960s.
Thulin was contracted to create plastic bags for a Swedish company. He was then applauded for his simple but tough plastic bag creation in 1965. From then on, many other manufacturers have adopted the methods of Thulin and added a few integrations and improvements so that they can create better products.
Manufacturing Process and a Few Variations
The primary thing that is very crucial when it comes to manufacturing poly bags is heat.
Heat is important as it ensures that the edges are sealed to create a bag. The process involves small pellets of polyethylene being melted and shaped into a material that is clear and bendable. This material is then cut in a specific way and then sealed on one side to finally produce the bags.
Today, polybags come in various sizes, shapes, and designs. They are even customized to serve specific purposes. There are poly bags that come with gussets that increase the carrying capacity of the bag. Some bags also have handles for better carrying. There are even bags that contains zippers and re-sealable strips that comes handy when the item stored in the bag is being taken in and out for a couple of times.
Advantages of Poly Bags
Poly bags are very advantageous in a lot of ways. First of all, they are cost-efficient because they only use fewer materials compared to other different shipping supplies. Compared to cartons and cardboard boxes, poly bags can actually have a larger storage volume while maintaining a low price.
It is also very advantageous when we talk about the environmental aspect of things. Poly bags are known to be easy to recycle. Other shipping materials might just become wasteful. But, poly bags use materials efficiently and they only occupy less space. Hence, you will be helping the environment when you use poly bags for commercial or individual purposes.
If you are looking for a safe and secure way to ship and store your items for your customers, a custom poly bag can be a smart choice. They are efficient because of their ability to store more items while occupying less space. Poly bags can also be customized in order to help with your branding efforts.
