Plastic Envelopes

Shield vital paperwork, student assignments, tax documents, and craft supplies from surface moisture, ink smudges, and accidental folds. JAM Paper plastic envelopes are manufactured from heavy-gauge, tear-resistant polypropylene engineered for dependable, repeated use in the classroom, home office, or commercial workspace, built to last season after season.

Translucent finishes allow you to view contents at a glance without opening the flap, while opaque solid colors keep confidential financial records private inside shared desk drawers or transport totes. Durable sonic-welded seams prevent edges from splitting, even under heavy daily loads.

Select the closure that matches your routine: classic button-and-string ties, quick snap buttons, airtight slide zippers, or reusable hook-and-loop coins. We carry slim document sleeves for individual contracts alongside expanding pleated gussets that easily hold thick textbooks, bound catalogs, project files, and loose desk supplies.

Plastic envelopes are highly versatile and are primarily used for protecting, organizing, and transporting documents. They are popular for organizing office paperwork, safely storing craft and school supplies, protecting important documents from water damage, and shipping or mailing lightweight items.

Yes, the material used to make plastic envelopes (typically polyethylene or polypropylene) is inherently waterproof and tear-resistant. This makes them excellent for protecting sensitive documents from rain, spills, or moisture during shipping and storage. However, keep in mind that unless they have a sealed zip closure, the edges or flaps are not 100% airtight or submersible.

Yes, you can mail plastic envelopes. Because they are lightweight and durable, they are a great cost-effective shipping solution for small items and documents. However, keep in mind that the postal service may classify them as "non-machinable" because of their slick surface or bulky closures (like buttons or snaps), which can sometimes require a slightly higher postage rate.

Yes, you can write on a plastic envelope using a permanent marker (like a Sharpie). However, if you plan to reuse the envelope for different purposes, it is highly recommended to use adhesive labels or write-on sticker strips, as permanent marker is difficult to remove from the plastic surface.

Plastic envelopes offer several distinct advantages over traditional paper envelopes. They are significantly more durable, tear-proof, and water-resistant, which guarantees that the contents remain pristine. Additionally, many plastic envelopes are clear or translucent, allowing you to quickly identify what is inside without having to open them—making them ideal for filing and organization.

Yes! Unlike paper envelopes that are often torn open and thrown away, plastic envelopes are designed for long-term use. Their durable material and resealable closures make them an eco-friendly option that can be used over and over again for storage, filing, or inter-office mail.
