Frequently Asked Questions

What is your return/exchange policy?

Quality inspection is conducted upon receipt. Claims must be submitted within 7 days of receiving goods. Defective products are eligible for free replacements. Please provide photos and order details when filing a claim.

What materials are used for corrugated mailer envelopes?

Corrugated mailer envelopes are made from EE-flute, BE-flute, FF-flute, F-flute, E-flute, B-flute Corrugated Board + Coated Paper. The E/B Flute provides superior compression strength and edgewise crush resistance for reliable shipping protection. The envelope flap uses a friction-fit groove design that secures without tape or adhesive. Stored flat when not in use to save warehouse space.

What is the weight capacity of corrugated mailer envelopes?

Our corrugated mailer envelopes support up to 10kg depending on the E/B Flute board grade and envelope size. Reinforced corner walls and double-wall construction are available for heavier items like books, shoes, or heavy accessories.

How does the envelope flap mechanism work?

The envelope flap opens and closes along pre-scored grooves with a friction-fit design that holds securely without tape or adhesive. For heavier shipments, self-locking tab options provide additional security. Assembly is quick and requires no tools.

How durable is the envelope flap closure?

Our corrugated mailer envelope flap is designed for repeated opening and closing without degradation. The friction-fit groove maintains closure integrity through standard shipping handling. For high-vibration or heavy-load shipping, reinforced flap options are available to prevent accidental opening.

What printing and finishing options are available?

We offer offset printing, flexographic printing, embossing/debossing, foil stamping (gold/silver), spot UV, and soft-touch lamination for premium appearance.

What is the minimum order quantity?

MOQ is 500-1500 pieces for standard sizes. For custom sizes or materials, MOQ starts at 1,000 pieces. Sample orders of 5-10 pieces are available.

Can mailer envelopes be customized with logos?

Yes, we offer custom logo printing via offset or flexographic printing. Embossing, debossing, and foil stamping are available for premium branding effects.

What industries use corrugated mailer envelopes?

Corrugated mailer envelopes are popular for cosmetics, skincare, jewelry, watches, electronics accessories, confectionery, tea packaging, and e-commerce retail packaging.

Are mailer envelopes eco-friendly?

Yes, we use recyclable cardstocks and water-based inks. FSC-compliant materials are available upon request. Biodegradable foam alternatives are available.
