Frequently Asked Questions
Are kraft bubble mailers recyclable?
The kraft-paper exterior is recyclable in many curbside programs, but the inner bubble padding is usually plastic and may prevent recycling as-is. Check your local recycling rules; some areas accept mixed-material mailers at specialized drop-off points. If recycling is a must, look for mailers labeled fully recyclable or compostable.
How do I know which size to buy?
Measure the item with any packaging you plan to include and compare to the product's usable interior dimensions. Allow extra space for padding and avoid forcing bulky items into a tight mailer. When in doubt, choose a slightly larger size to reduce the risk of tearing or bending.
What if the adhesive doesn't hold?
Some buyers report inconsistent adhesive performance across packs. For important shipments, reinforce the seal with packing tape or use a label across the flap. Testing one pack before buying in bulk helps avoid problems.
