Jiffy Tuffgard Extreme® Bubble Lined Poly Mailers

Start with the outside mailer dimensions and subtract practical space for both product thickness and the cushioning layer. Avoid forcing rigid items into the envelope or concentrating weight at the seams. The product should remain clear of the adhesive area and should not create outward pressure on the flap.

The 5/16-inch air-cell construction is thicker than selected options in the broader poly cushioned mailer family. Thickness alone does not determine suitability. Product weight, corners, fragility and the distribution route still control whether a flexible package is enough.

Cover sharp edges, fasteners and protrusions that could puncture the film or cushioning. Keep the closure surface clean and dry, remove the liner at the final step and apply even pressure across the strip. Reject mailers with damaged seams, contaminated adhesive or punctured exteriors.

TuffGard Extreme mailers remain flexible despite the thicker cushioning. Use a corrugated package when the product requires bending control, stacking structure or stronger crush protection. Do not treat the poly exterior or self-seal closure as proof of waterproof or tamper-evident performance.
