Difference Between Poly mailers and Plastic Bags

What are Poly mailers and Plastic Bags?

The poly mailers and plastic bags are two commonly used packaging materials serving different purposes and have discrete characteristics. Poly mailers are precisely designed for shipping items. They are lightweight, durable, and offer protection against water and tampering.

On the other hand, plastic packaging bags are normally used for retail purposes, like carrying groceries or storing household items. They are often made from low-density polyethylene and come in various sizes and thicknesses.

  • Material and Cost

Poly mailers and plastic bags are made from polyethylene, so they’re both plastics. Polyethylene is a type of plastic that can be recycled, but it’s more challenging to recycle than other plastic.

Poly mailers are more expensive than plastic packaging bags because they’re thicker and stronger than the thin film used in standard bags. They also have an adhesive strip on the back, so you don’t have to tape them shut with tape or staples like standard bags; fold over one end and stick it down.

Plastic bags are cheaper than poly mailers because they’re thinner and less material is used to make them. This makes them less durable overall than poly mailers.

  • Size, Shape, and Weight

Poly mailers and plastic bag products are used for packaging. However, they have several differences between them. Poly mailers are made from a thin, flexible film material that can be folded or rolled up easily and stored until needed. Plastic bags are flat rectangular plastic containers heavier than poly mailers but more flexible.

Plastic Bags come in many sizes, shapes, and weights. They’re often used to pack items like clothes or food items purchased from grocery stores or supermarkets because they’re cheap enough to throw away after use.

Poly Mailers are larger than most plastic bags – though there are exceptions – so they are usually only used for packing groceries if you buy large quantities at once.

  • Environmentally Friendly

Poly mailer bags are made from recycled materials, while plastic bags are made from petroleum. This means that poly mailer bags are more environmentally friendly than plastic bags.

Another reason why people often prefer to use poly mailers is because they can be recycled. You need to separate your recyclables and clean them before putting them in the recycling bin so they don’t contaminate other items. Plastic bags cannot be recycled due to their size, shape, and thickness.

However, if you have any leftovers after packing your items up for shipping purposes, then feel free to throw them away in regular garbage bins instead of trying hard not to toss them out otherwise.

  • Product Protection and Durability

Poly mailers are stronger and more durable than plastic bags. Poly mailers’ thicker construction enhances protection by reducing the risk of tearing or puncturing during shipping, safeguarding your products effectively. They excel at shipping fragile items such as glassware or electronics, as they remain intact even when dropped during transit.

Plastic bags typically store food items such as cereal and chips. However, some people use them as packaging materials when sending items via mail because of their low cost.

Plastic bags may not be the most durable option, but they offer some benefits over poly mailers: their ability to hold liquids without leaking through onto other objects inside your package.

  • Customization

Flexibility is another benefit of plastic packaging bags. You can order them in any size and shape, including custom-made ones.

Additionally, you can choose from various colors and even have your logo printed on them for added brand recognition. However, by working with Ideal PKG a custom plastic bags manufacturer, you can have uniquely tailored bags that meet your specific requirements and enhance your brand image.

Modification is also possible with poly mailers; however, it’s more flexible than the customization options for plastic bags because they are generally available only in standard sizes and shapes. The same goes for color selection. Finding many other options besides black or white for poly mailers is hard.

  • Choice

Poly mailers are the best packaging alternative for shipping delicate items, while plastic bags are great for storing food. They are durable than plastic bags and can be used for shipping and storage. Poly mailers offer added benefits for delicate or mailed items due to their superior tear resistance compared to plastic bags.

Poly mailers are generally made of polyethylene, making them waterproof and able to withstand moisture better than paper or other materials. This is an excellent choice if you’re looking for something that will protect your items from moisture.

If you want something lightweight but strong enough to protect fragile items like glassware or electronics, then a poly mailer is likely your best option.


Poly mailers are made of polyethylene, while plastic packaging bags use a different material, polyvinyl chloride. Polyethylene is known for being more durable than PVC, so it’s better suited for carrying heavier items or those which might get wet in transit (like electronics). However, both products have their pros and cons when compared side-by-side.
