A bulk pack of 100 helps maintain stock levels for businesses with regular shipping volumes.

How to use

Place the item into the mailer so it sits flat against the bubble lining and does not exceed the internal dimensions. Remove the protective strip from the adhesive flap and press firmly along the entire closure to form a secure seal. For added security or when shipping heavier contents, use a strip of tamper-evident tape over the flap or label the package with tracking information. Check that labels and addresses are clearly visible on the white exterior before handing to the carrier.

Usage recommendations

For best protection, use the mailer for items that fit comfortably within the internal dimensions and benefit from bubble cushioning; avoid overfilling. Store the pack in a dry environment away from direct sunlight to preserve adhesive effectiveness. When shipping electronics, include appropriate anti-static precautions if required and confirm carrier size and weight limits to optimize postage.
