Polythene Mailing Bags – ideal solution for e-commerce and logistics

Polythene mailing bags are robust foil envelopes made from high-quality LDPE film, ensuring complete security for the products being sent. With their water resistance, strong adhesive strip and lightweight construction, foil envelopes are an excellent choice for e-commerce, logistics, warehousing and document and goods shipping companies.

They are a common way to optimise packaging costs where the product does not require stiffened packaging and is not prone to damage from bumps or shocks such as: clothing, small leather goods, teddy bears, books, printed magazines or textiles.

FAQ

How do you store foil packets to preserve their quality?

Foil packs are best stored at 10°C – 25°C, away from:
– moisture and extreme temperatures
– direct sunlight
– chemicals which may weaken the film

Storage under appropriate conditions ensures the flexibility and durability of the foil packs.

Are foil packs safe for document packaging?

Yes, courier foil packs are often used to send documents, contracts, invoices or tender offers. If you want extra protection, choose foil packs with a double layer of foil or use an extra bubble envelope inside the foil pack.

What is the difference between foil packets and bubble envelopes?

Courier foil envelopes – thin, lightweight, ideal for documents, clothing and books.
Bubble envelopes – have an extra layer of bubble wrap for greater protection against mechanical damage (ideal for electronics, glassware, fine ceramics).

If you are sending fragile items, consider bubble envelopes or an extra layer of protective foam.

Are foil packs available in colours other than white?

Yes! The standard colours of the foil packs are white, black and transparent, but we can make foil packs in any colour on request, and also add an imprint of your logo or other company graphics.

What are the best practices for packaging in foil packs?

To ensure safe shipping, follow these rules:

– do not overload the foil pack – choose the right size for your product
– close the adhesive strip tightly to avoid opening in transit
– add extra protection for fragile items – e.g. bubble wrap or PE foam
– place the address label on a flat surface – you avoid problems with the readability of the barcode

Following these practices reduces the risk of damage and increases customer satisfaction.
