What are letter & bubble envelopes
Letter envelopes are simple flat paper containers for documents and mail. They’re made from regular paper or cardboard and come in standard business sizes. You can print your company logo, address, and colors directly on them. They work great for invoices, contracts, marketing letters, and official documents.
Bubble envelopes are padded mailers with protective air cushions inside. The outside looks like a regular envelope, but the inside has small air bubbles that protect fragile items during shipping. They’re perfect for jewelry, electronics, cosmetics, small parts, and anything that could break or get damaged. The bubble lining keeps products safe while still looking professional on the outside.
Both types can be customized with your branding and come in different sizes. Letter envelopes range from small business card size to large document size. Bubble envelopes go from tiny jewelry pouches to big book-sized mailers.
What’s the benefit
Custom envelopes make every piece of mail look professional and branded. Recipients see your logo before opening anything, which builds trust and recognition. Your business looks established and reliable.
For shipping products, bubble envelopes protect items while advertising your brand. Customers remember companies that package safely. Your shipments stand out from plain brown packages. It’s smart marketing combined with product protection in one solution.
Bubble mailers use air-filled plastic bubbles for protection. You can see and feel the individual bubbles inside. Padded mailers use other materials like foam, fabric, or recycled paper stuffing. The padding feels softer and more uniform.
Protection Level: Bubble mailers give good protection for lightweight fragile items like jewelry or phone cases. Padded mailers offer better cushioning for heavier or more delicate items. The foam or fabric padding absorbs impact better than air bubbles.
Cost Difference: Bubble mailers cost less to make and buy. The bubble wrap inside is cheap and easy to produce. Padded mailers cost more because foam and fabric materials are more expensive.
Environmental Impact: Padded mailers are often more eco-friendly. Many use recycled materials or biodegradable foam. Bubble mailers use plastic bubbles that don’t break down naturally. However, both can be reused multiple times.
Appearance: Both look similar from the outside. The main difference is what you feel when you squeeze them. Bubble mailers feel bumpy with air pockets. Padded mailers feel smooth and squishy.
Best Uses: Use bubble mailers for light items that need basic protection. Use padded mailers for valuable or heavy items that need extra cushioning. Electronics, glassware, and expensive jewelry work better with padded mailers.
The choice depends on what you’re shipping, your budget, and how much protection you need.
What is the difference between padded and bubble mailers?
Best Uses:
- Bubble mailers: Clothing, documents, jewelry, small electronics, flat items
- Shipping boxes: Fragile items, multiple products, heavy items, anything valuable
Environmental Impact: Mailers use less material and create less waste. Boxes use more cardboard but are easier to recycle and reuse.
Choose mailers for simple, lightweight shipments. Choose boxes when protection and presentation matter more than cost.
What is the difference between bubble mailer and shipping box?
Shape and structure: Bubble mailers are flat, flexible envelopes that bend and fold. Shipping boxes are rigid, square or rectangular containers that hold their shape. Mailers take up less space when empty.
Protection level: Shipping boxes offer much better protection. They have strong walls and can handle heavy items without crushing. Bubble mailers only protect against scratches and light impacts.
Weight capacity: Boxes can hold heavy items – books, electronics, multiple products. Bubble mailers work best for lightweight items under 2-3 pounds. Anything heavier might tear the mailer.
Storage space: Items in boxes don’t get compressed during shipping. Bubble mailers can squeeze and flatten, which might damage some products. Boxes keep items in their original shape.
Shipping cost: Bubble mailers cost less to ship because they’re lighter and take up less space. Boxes cost more due to their size and weight, even when empty.
Professional appearance: Boxes look more professional and substantial. Customers feel like they’re getting something valuable. Mailers look more casual and everyday.
No, bubble mailers cost less than shipping boxes. The mailers themselves are cheaper to buy, and they cost less to ship because they're lighter. Boxes cost more upfront and add extra weight to your shipping costs. If you're sending lightweight items, mailers will save you money.
Bubble mailers are usually better for small businesses. They cost less, take up less storage space, and work great for most products small businesses sell - like jewelry, accessories, or small electronics. Only switch to boxes if you're shipping fragile or heavy items that need extra protection.
Common sizes range from 4" x 8" for tiny items like earrings, up to 14" x 20" for large documents or clothing. Most small businesses use 6" x 10" for general items, 7" x 12" for books or phone cases, and 8" x 12" for clothing or small electronics. Pick a size that gives your product about 1 inch of space on all sides.
Yes, we can print your logo, colors, and contact information on both bubble mailers and letter envelopes. Custom printing makes your packages look professional and helps customers remember your brand. It's like turning every shipment into a walking advertisement for your business.
Letter envelopes made of paper can go straight into regular paper recycling. Bubble mailers are trickier - you need to separate the paper outer layer from the plastic bubble lining. The paper part can be recycled, but the plastic bubbles usually can't in regular recycling programs. Some areas have special plastic film recycling at grocery stores.
Poly mailers are lightweight plastic shipping bags, usually white or gray. They're waterproof and tear-resistant, making them great for clothing or non-fragile items. They cost even less than bubble mailers and weigh almost nothing for shipping. Many online clothing stores use poly mailers because they protect against moisture and keep shipping costs low.

How XiangGe Package produce letter & bubble envelopes
Below are our letter & bubble envelope boxes with logo manufacturing process:
Step 1: Paper Preparation. Start by cutting large paper rolls into sheets that match your envelope size. For letter envelopes, use regular paper or cardboard. For bubble envelopes, prepare both the outer paper layer and the inner bubble wrap material that will provide cushioning protection.
Step 2: Design Printing. Print customer logos and designs onto the paper sheets using offset or digital printing machines. Apply the correct colors and ensure all text is clear and properly positioned. Let the printed sheets dry completely before moving to the next manufacturing step.
Step 3: Cutting and Shaping. Use die-cutting machines to cut the printed sheets into the exact envelope shapes. Score fold lines where the envelope will bend and crease. Cut precise holes for handles if needed. Stack all cut pieces in proper order for assembly work.
Step 4: Assembly and Gluing. Fold the envelope pieces along the scored lines and apply strong adhesive to create seams. For bubble envelopes, attach the bubble wrap lining to the inside before sealing. Press all seams firmly and let glue cure for proper bonding strength.
The manufacturing process typically takes 5-7 days from raw materials to finished envelopes, depending on order complexity and quantity requirements.
