Let’s find out.

Food-Industrial-Bag-CollageWhat are the different materials available?
Autobag has many different options when it comes to poly bags that are specifically designed to work with their different poly bagging systems. These bags are storefront ready and can be printed in full color. Just a few of the options are Linear Low Density Polyethylene, Low Density Polyethylene Films, High Density Polyethylene Film, Polypropylene Film, and Anti-Fog. There are many more materials to choose from, and highly likely there will be bagging materials that fit your company’s needs.

  • Linear Low Density Polyethylene is strong material, durable, and has clear through opaque combinations ranging from blank to custom printed. It is ideal for packaging hardware, automotive parts, food, craft items, medical devices, electronic components, and many more.
  • Low Density Polyethylene Films are durable, versatile, and have different printing characteristics. They are ideal for retail packaging, hardware, fasteners, automotive parts, medical, frozen foods, mail order fulfillment, and others.
  • High Density Polyethylene Film has reduced chemical additives and good permeability. It is also scratch-resistant. This material is used for packaging medical, food, sporting goods and other applications where chemical additives may react with the product inside.
  • Polypropylene Film has the best bag clarity, good seal strength, and resists odor transfer. It is used for foods, pet supplies, and other retail packaging.
  • Anti-Fog materials are best for fresh produce applications. When condensation forms within the bag caused by product respiration, the material does not allow the moisture to form water droplets. This provides great clarity and strength.

Which bag dimension and thickness is best?
Choosing the right poly bag for your product can be difficult. It depends on the weight, size, shape, pieces going in a bag, and other factors. Autobag’s poly bags range in size and mil thickness.
