E2 Envelopes – Padded & Bubble Mailers | Secure Shipping

You’ve just spent hours carefully wrapping a fragile necklace for your best customer. You drop it in a flimsy envelope, cross your fingers, and pray it survives the journey. Two days later: “Package arrived damaged. Requesting a refund.” Sound familiar? Stop gambling with cheap mailers. E2 padded envelopes aren’t just packaging – they’re your reputation’s bodyguard. With military-grade bubble armor, Royal Mail-compliant sizing, and eco-materials that won’t trash the planet, these aren’t envelopes. They’re insurance. Keep reading – because your next 5-star review is already in the mail.

What Are E2 Envelopes?

E2 envelopes are the Swiss Army knives of shipping – 220x260mm of exactly what you wish you’d used last time. Designed to fit Royal Mail’s Large Letter slot (translation: no surprise surcharges), these aren’t your grandma’s stationery. We’re talking White Kraft paper tougher than a rugby prop forward, lined with bubble wrap that’s survived our CEO’s “office golf” stress tests (don’t ask).

But here’s why you’re still reading: They’re the only FSC-certified padded mailer that lets you check every box:

•  Cheaper postage than parcels
•  No more “Received damaged” emails
•  Guilt-free unboxing (100% recyclable)
•  No tape wars (peel-seal strip = 3-second close)

Still using plastic poly mailers? That’s like bringing a water pistol to a warehouse fire. Let’s fix that.

What Makes E2 Padded Envelopes Stand Out?

Perfect Dimensions for Versatility

E2 envelopes are crafted with precision to accommodate a wide range of items. Their internal dimensions (220mm x 260mm for Mail Lite and 220mm x 265mm for Featherpost) ensure snug protection for small but valuable goods like DVDs, small components, or giftware. The external dimensions (240mm x 275mm) meet Royal Mail’s Large Letter classification, making them cost-effective for shipping while maximizing usability.

Built to Protect

The outer layer is made from white Kraft paper—a recyclable material that’s writable and non-coated—allowing you to personalize your packages while staying eco-conscious. Inside, the AirCap bubble lining (crafted from 60% recycled content) absorbs shocks and prevents damage during transit. Whether it’s a fragile heirloom or an intricate electronic component, E2 envelopes provide unmatched protection.

Effortless Sealing and Tamper Evidence

Say goodbye to cumbersome packaging methods. E2 padded envelopes feature a peel-and-seal adhesive strip for quick closure and an easy-open tear strip for secure yet effortless unpacking. This tamper-evident design ensures that your items remain safe from unauthorized access while enhancing the unboxing experience.

Frequently Ask Question’s (FAQ’s)

1. What are the exact dimensions of E2 envelopes?
E2 envelopes have internal dimensions of 220mm x 260mm (Mail Lite version) or 220mm x 265mm (Featherpost). Externally, they measure 240mm x 275mm. Fun fact: This fits 12 standard DVDs or 8 iPhone boxes with padding.

2. Are E2 envelopes Royal Mail Large Letter compliant?
Yes – when using our Mail Lite version (220x260mm), they meet Royal Mail’s Large Letter size limits. This keeps postage costs at £1.15 instead of £2.85 for parcels. Pro tip: Avoid Featherpost for Large Letter postage – the extra 5mm depth risks surcharges.

3. Can E2 padded envelopes be recycled?
100%. Unlike plastic poly mailers, our E2 envelopes use FSC-certified Kraft paper and 60% recycled bubble lining. Toss the entire envelope in your household recycling – no separating materials.

4. How much weight can E2 padded envelopes hold?
They’re tested for 2kg, but we recommend ≤1.5kg for optimal protection. The bubble lining absorbs shocks from drops up to 1.2m – perfect for ceramics, electronics, or luxury candles.

5. What’s the difference between E2 and C4/C5 envelopes?

E2 (220x260mm): Best for bulky small items (jewelry, cosmetics).
C4 (229x324mm): Fits A4 documents unfolded.
C5 (162x229mm): Slimmer, cheaper postage.
Use E2 for protection, C4/C5 for documents.

6. Are E2 bubble mailers waterproof?
They’re weather-resistant, not fully waterproof. The Kraft paper can handle light rain, but for monsoons, add a poly bag. Better yet: Use our water-activated gummed tape for extra sealing.

7. Do E2 envelopes come with self-seal adhesive?
Yes – our tamper-evident peel-and-seal strip requires no tape. It bonds instantly, even in freezing temperatures, and leaves a visible “VOID” pattern if opened.

8. Where can I buy E2 envelopes in bulk?
We supply packs from 10 to 2,000 units, with bulk discounts at 500+. Unlike competitors, we offer free storage for 30 days if you’re tight on space.

9. Are E2 envelopes eco-friendly?
They’re FSC-certified (sustainable forests) and use 60% recycled bubble wrap. For every 100 envelopes sold, we plant 3 trees via Ecologi. Plastic mailers? They’ll outlive your grandkids in landfills.

10. Can E2 envelopes be used for international shipping?
Absolutely – they’re compliant with USPS, DHL, and FedEx size guidelines. Just ensure items ≤2cm thick to avoid parcel fees.
