FAQ About Shipping Mailers & Bags
Q: Are your poly mailers completely opaque for privacy?
A: Yes. Our PE poly mailers feature a high-opacity inner lining (usually gray or black) to ensure that the contents are 100% invisible, providing maximum privacy and security for high-value retail items.
Q: What is the shelf life of your Compostable Mailer Bags?
A: Because they are made from plant-based polymers (like PBAT and PLA), we recommend using them within 10-12 months. Store them in a cool, dry place away from direct sunlight to maintain their optimal tensile strength.
Q: Do Padded Bubble Mailers provide better protection than boxes?
A: For small, flat, or semi-fragile items, bubble mailers are often superior because they provide adequate cushioning while being significantly lighter and thinner than boxes, saving you up to 30-50% on international air freight costs.
Q: Can we order custom sizes for clear apparel bags?
A: Absolutely. We can customize the dimensions, film thickness, and include features like dual adhesive strips (for returns) or specific warning labels (suffocation warnings) required by Amazon FBA or other global platforms.
