Sealing Science·Mistake Avoidance·ISTA Certified｜Free Video Demo
5 Professional Steps for Optimal Protection
Item Preparation
Wrap sharp edges with foam corners (e.g., phone cases)
Place small items in anti-static bags first
Select Mailer Size
Item should occupy 70% of internal space
Allow 2cm clearance on all sides
Insertion Technique
Place heaviest side against bubble layer
Position bubbles facing inward for direct cushioning
Sealing Protocol
Peel adhesive strip fully
Press firmly along entire flap (10N pressure)
Reinforce seams with 5cm tape on each end
Labeling Best Practices
Apply label over seam tape (prevents peeling)
Cover with transparent tape if shipping in rain
Pro Tip: For >500g items, use double-layer mailers with cross-pattern taping!

Can You Recycle Bubble Wrap? Bubble wrap is technically recyclable, but its recycling process differs from regular plastics due to its LLDPE (Low-Density Polyethylene) composition and air-filled structure.
Key Recycling Facts: ✔ Material Type: Made from #4 plastic (LDPE/LLDPE), accepted at specialized recycling facilities ✔ Preparation Required: Must be clean & dry – no tape, labels, or debris ✔ Drop-off Locations: Most supermarkets & big-box stores (e.g., Walmart, Target) have plastic film bins ✔ Upcycling Ideas: Reuse for packaging, DIY insulation, or craft projects
Challenges in Recycling:
Not Curbside Recyclable: Most municipal programs reject it due to sorting issues
Contamination Risk: Food residue or mixed materials make it non-recyclable
Specialized Process: Requires separate collection and pelletizing
