Product Information

Full details

The GoSecure Bubble Envelope (Size 9) is an ideal shipping solution for e-commerce businesses and individuals who need reliable, cushioned protection for fragile or document-based items during transit. It offers the key benefit of a shock-absorbing bubble-lined interior combined with a professional white paper finish; however, the 75gsm weight means it is best suited for lightweight to medium-weight parcels rather than heavy, sharp-edged objects.

FAQs

What are the exact internal dimensions?

The internal dimensions are 290x435mm, which provides ample space for large documents or soft goods.

Are these envelopes waterproof?

They are made of paper and offer no protection against moisture or water; keep them dry during storage and transport.

Can I reuse these envelopes?

The peel and seal closure is designed for a single-use secure seal. Attempting to reuse them may compromise the structural integrity.

What does 75gsm MG grade paper mean?

75gsm refers to the weight of the paper (grams per square meter), indicating a durable yet lightweight stock suitable for mailers.

How do I recycle these?

Because they are 100% recyclable, you can place them in your standard paper recycling bin, though it is best practice to remove any external shipping labels first.

Troubleshooting

Adhesive strip not sticking properly

Ensure the surface of the envelope is clean and free of dust or debris before peeling the strip; apply firm pressure for 5-10 seconds after sealing.

Envelope bulging or difficult to close

The item inside may be too thick. Ensure you are not exceeding the internal 290x435mm dimensions or the physical thickness limits of the envelope.

Pros and Cons

Pros

  • Excellent internal padding for fragile protection
  • Convenient peel and seal closure saves time during packing
  • Environmentally friendly 100% recyclable material
  • Professional white exterior finish ideal for branding
  • Large internal volume for versatile shipping needs

Cons

  • Not suitable for extremely heavy or jagged items
  • Paper exterior can be susceptible to tearing if punctured by sharp objects
  • Size 9 may be too large for small individual items without extra internal packaging

Setup, Compatibility & Care

Using these envelopes is straightforward. Simply insert your item into the envelope, peel away the protective strip covering the adhesive, and press the flap firmly against the body of the envelope to create a secure seal.

Best practices for care and shipping:

  • Ensure items are flat or flexible to maximize the efficiency of the bubble interior.
  • Always press firmly across the adhesive strip to ensure a full bond.
  • Store envelopes in a cool, dry place to maintain the integrity of the adhesive and the paper.
  • If shipping internationally, verify that the external dimensions (320x450mm) meet your courier's parcel size requirements.
