Advantages

These protective polyethylene envelopes combine low weight and compact size to reduce postage costs and storage space. The 25 g film provides basic resistance against moisture and dirt while remaining flexible for easy handling and folding. The self-adhesive closure offers a tamper-evident seal that simplifies packing and improves shipment security without additional tape. The neutral exterior surface is suitable for printing shipping labels and handling marks.

Key specifications

• Material: polyethylene film
• Film weight: 25 g
• External dimensions: 240 x 275 mm
• Closure type: self-adhesive, tamper-evident

How to use

Place the item flat inside the envelope, ensuring edges and corners are protected from sharp contact. Remove the protective strip from the adhesive flap, fold the flap down and press firmly along the seal to activate the self-adhesive closure and ensure a tamper-evident bond.

Recommendations

Use these mailing bags for lightweight, non-fragile items and documents where cost-effective, moisture-resistant packaging is sufficient. Do not rely on these envelopes for sharp-edged or heavy products without additional protection; choose reinforced packaging for fragile or high-value items. Store unopened packs in a cool, dry place away from direct sunlight to preserve adhesive performance.
