RAADHUIS Versandtasche COEX PE 450 x 550 mm 50 µm white tear-resistant opaque

RAADHUIS Versandtasche COEX PE 450 x 550 mm 50 µm white tear-resistant opaque is a single-piece poly mailer designed for secure postal and courier shipping of documents and small goods. Made from coextruded polyethylene (COEX-PE) with a 50 µm wall thickness, this white mailer is tear-resistant and fully opaque to protect contents from moisture and visual inspection during transit. The flap closure provides a simple seal to keep items secure while remaining lightweight for cost-efficient postage.

Advantages

The COEX-PE construction combines multiple polymer layers to deliver improved strength and puncture resistance compared with standard single-layer films. At 50 µm thickness the mailer balances durability and flexibility, reducing the risk of tearing while allowing items to conform inside the package. The opaque white surface prevents visibility of contents and offers a clean appearance suitable for business mailing. Its lightweight design keeps shipping costs lower than rigid packaging while providing moisture resistance and a reliable closure.

Suitable for

• Shipping folded documents, catalogs, and leaflets that require privacy
• Sending textiles, small clothing items, or soft accessories
• Mailing non-fragile goods where puncture resistance and moisture protection are needed
• Postal and courier shipments where lightweight packaging reduces postage costs

When it may not be suitable

This poly mailer is not intended for heavy, sharp, or fragile items that require rigid protection or cushioning; such items may need boxes with internal padding or bubble wrap. It is also not a tamper-evident security bag—while the closure secures contents, specialized tamper-proof solutions should be used when higher security is required.

Key specifications

• Material: Coextruded polyethylene (COEX-PE)
• Dimensions: 450 x 550 mm
• Wall thickness: 50 µm
• Color and opacity: White, opaque
• Closure: Flap seal (self-adhesive or fold-over; check product package)
• Packed: Single-piece mailer

How to use

Insert the item to be mailed so it lies flat and does not create excessive stress on the edges. Remove any protective strip from the flap if the closure is self-adhesive, fold and press firmly along the seal to close. For folded or soft items, smooth out air pockets to reduce bulk; for heavier contents consider reinforcing the edges with tape. Clearly attach the mailing label and any required customs documentation to the outside surface following postal service guidelines.

What to consider before purchase

• Assess item size and weight to ensure 450 x 550 mm and 50 µm thickness provide adequate protection
• Consider whether additional padding or a rigid box is needed for fragile or sharp items
• Confirm the closure type on the product package if a tamper-evident or resealable option is required
• Verify postal and courier limitations for plastic mailers and any size or weight restrictions

Usage recommendations

For routine document and soft-goods shipments use these mailers as a lightweight, moisture-resistant option. When mailing items with edges or corners, add corner protection or wrap in an extra layer to avoid punctures. Store unused mailers flat in a dry place to preserve the adhesive and material integrity.
