What is a Poly Mailer?

If you haven’t heard of a poly mailer before, it is crucial to know what they are before deciding they are the right choice for you. A poly mailer is a lightweight plastic envelope made of plastic. This moisture-resistant and durable mailer may look thin, but it offers a layer of protection that will ensure the delivery of your product arrives in perfect condition on your customer’s doorstep.

What is a Poly Mailer Made of? 

Poly mailers are made with polyethylene film, which is also known as plastic. It is the lightest variant of all the polyethylenes. This plastic lightweight mailer can withstand the coldest weather conditions, such as rain or snow, and the warmest weather conditions, like high humidity.

How Much is a Poly Mailer

One of the things that makes a poly mailer so appealing is how affordable it is. Their cost is the most significant advantage the poly mailer has over the other options out there. The average cost is about twenty-five cents per mailer when buying in bulk and about $1.25 if buying a single unit. This low cost makes it an easy choice for many. 

Are There Different Sizes of Poly Mailers

Poly mailers come in numerous sizes, but the standard size is a 10” x 13” mailer. While you can purchase poly mailers in bigger or smaller sizes, choosing based on what you plan to put inside them is essential. Make sure to measure the length and width of your item before purchasing your poly mailer to ensure you buy the proper size necessary.

What are the Production Stages of Poly Bags?

  • Blown Film
  • Plastic Rolls

The Blown Film Extrusion Process

The blown film extrusion process is the first step in creating a polybag. First, tiny plastic pellets (also known as resin) are melted down until they have become pliable and infused. Once the desired pliability has been reached, they are pressed through a gap to form a continuous plastic tube. This plastic tube is pinched off at one end and then inflated and stretched to the desired size and thickness.

After the blown film extrusion process is complete, those plastic rolls are transformed into poly bags. To do this, the rolls of plastic tubing are fed into a machine that draws the material out to the desired length. The machine will then place a seal on the material at said length, cutting it off to make an individual bag. This process is repeated until the desired number of poly bags has been completed.

Are There Different Color Poly Bags? 

  • White
  • Clear

Custom poly bags can be of any color or design. These bags have a complete design on them, adding a special touch to your package. Whether they say words such as “thank you,” have animal prints on them, or are specific to holidays, these custom bags are a great option.
