Common questions

Will these mailers protect products from moisture during shipping?
Yes. The 2.5 mil polyethylene construction provides moisture resistance to protect contents from humidity, rain, and water exposure during transit. However, these are not fully waterproof; for guaranteed water protection, consider our weatherproof mailer upgrades for high-value shipments.
Are the adhesive strips reliable, or will packages come open in transit?
The integrated self-seal adhesive strips are engineered for secure closure with a simple press-and-seal application. Ensure clean contact with the sealing strip for maximum adhesion. Most e-commerce brands report zero issues with package openings when properly sealed.
Can these 33-inch mailers accommodate different product sizes?
The 8.5 x 33" dimensions are optimized for long, narrow items like rolled textiles, scarves, and folded apparel. Products shorter than 33" will fit easily; the length is designed to minimize wasted space while maintaining professional appearance.
How many mailers are in each case, and what's the cost per unit at bulk?
Each case contains 100 individual mailers, making this an ideal bulk option for e-commerce brands shipping 20-40+ orders weekly. Per-unit costs decrease significantly with multi-case orders; contact our sales team for volume pricing and freight quotes.
