Poly Bags with Seal

A poly bag is a transparent bag with a self-seal closure designed for wholesale and inner packaging. It is used with secondary transit packaging, such as a poly mailer or shipping box, to keep items clean and separated in transit. These retail merchandise bags are made of soft, thin, and clear polyethylene. Particularly suitable for online and retail sales, they allow for scanning barcodes and quick and simple packaging, especially when fulfilling large orders with many different items. Poly bags may include those without print or pre-printed with a suffocation warning.

A poly mailer is a plastic envelope that ships durable and soft commodities. It is constructed from thin, lightweight, and sturdy polyethylene film that is waterproof and tamper-resistant.

A plastic bag is a general term covering traditional grocery bags, resealable bags, mailer bags, and more.

While many poly bags are not sustainable, EcoEnclose’s poly bags are. We promote circularity by using 100% recycled materials and ensuring that our bags are also recyclable. On top of this, they are domestically manufactured, reducing the carbon footprint associated with shipping. They are also BPA-free.

While poly bags can usually be taken to a designated drop-off location, we provide a take-back program where consumers without access to thin film recycling can return these bags to EcoEnclose.

We use LDPE (low-density polyethylene) instead of PVC, PP, or other types of plastic because it is more readily recyclable in the United States, more protective, and more sustainable overall. While it does have a slight opacity compared to polypropylene, its recyclability and stretchability make it a superior option.

Many people ask if we have degradable or biodegradable poly bags. We do not for a few key reasons. These plastics are often designed to degrade quickly, but like normal plastic, they cannot fully degrade. Instead, they quickly break down into microplastics. Other types will emit methane as they degrade, greatly contributing to greenhouse gas emissions.

As for bioplastics, they are typically made from virgin materials rather than recycled ones, and they can only be composted in an industrial facility. This makes them less sustainable than they at first seem.

Lay out the products you will be shipping on a table and measure the imaginary bounding box it would fit in. The two dimensions of your bag should exceed the largest two dimensions of your bounding box, plus a little extra room to compensate for the bag's expansion when it’s filled.

Once you have what you think is the perfect-sized bag, order a free sample to test them. This way, you can be 100% sure you have the size you need before buying in bulk.

As a frame of reference, we’ve compiled a table of common products shipped in our bags.

Yes - our poly bags are FDA-Compliant, meaning the product is compliant with FDA rules and regulations and is created with materials that are FDA-Approved. We recommend ordering case quantities if you plan to use these for direct food contact because our bundles are re-cased in a non-FDA compliant facility.
