Collection: Translucent Envelopes

Clear and translucent packaging that shows what's inside without committing to plastic. Postal Packaging's range covers cello bags, biodegradable glassine envelopes, and EN13432-certified compostable PLA bags, suitable for greetings cards, invitations, retail display, seed packaging, artisan food, and confectionery. The semi-transparent or fully clear material makes the contents visible before opening, which works well for branded retail, craft markets, and gift stationery. Eco credentials vary by product: cellulose and PLA options are fully plant-based and compostable, while polypropylene cello bags offer clarity and durability for display use. Available in a range of sizes to suit everything from small seed packets to full A4 documents.

More About "Translucent Envelopes"

Translucent and Clear Packaging for Every Use

The defining feature of translucent packaging is visibility: contents can be seen or hinted at through the material, which changes how a product is presented and received. Whether that is a greetings card glimpsed through a crisp vellum envelope or a batch of seeds shown clearly in a compostable bag, the right translucent format communicates both the product and the care taken in presenting it.

Materials and Eco Credentials

Not all translucent packaging is plastic. Postal Packaging's range includes several genuinely eco-friendly formats alongside conventional options:

  • Glassine envelopes: semi-transparent, plant-based, biodegradable and suitable for direct food contact
  • PLA (polylactic acid) bags: crystal-clear, EN13432 certified compostable, ideal for confectionery, gifts, and food packaging
  • Cello bags (polypropylene): clear, food-safe, available with peel and seal or open-top formats, not biodegradable but recyclable in many areas

What to Use Translucent Packaging For

  • Greetings cards and invitations where the envelope adds to the presentation
  • Retail display packaging for handmade goods, crafts, and stationery
  • Seed, herb, and loose-leaf packaging requiring a food-safe transparent format
  • Confectionery, fudge, and artisan food presentation
  • Gift packaging where visibility of the contents is part of the appeal

Sizes and Formats

The range covers formats from small seed-packet bags up to C4 document envelopes, with peel and seal closure options on most lines. Compostable and biodegradable formats are available in standard envelope sizes including C6, C5, and DL.
