Product Handling
Storage & Care for Poly Mailers
Proper storage and handling help protect poly mailer film, adhesive closures, padded interiors, carton condition, and overall packaging performance before use in commercial shipping operations.
01
Keep Mailers Clean & Dry
Store cartons and unused mailers in clean, dry warehouse conditions and protect them from moisture, dust, debris, and other contaminants before packing.
02
Protect the Adhesive Strip
Keep self-sealing adhesive areas clean and covered until the mailer is ready for use. Avoid unnecessary contact with the adhesive before final packing and closure.
03
Avoid Excessive Heat
Keep poly mailers away from excessive heat, hot equipment, and prolonged exposure to conditions that could affect the polyethylene film or adhesive system.
04
Protect from Direct Sunlight
Store cartons away from prolonged direct sunlight and strong UV exposure whenever possible to help maintain packaging condition during warehouse storage.
Before Packing
Select the Right Size
Choose a mailer that allows the product to fit without excessive stretching or unnecessary empty space.
During Packing
Seal on a Clean Surface
Keep the closure area free from dust, moisture, and product material before pressing the adhesive seal closed.
Warehouse Practice
Rotate Inventory
Use normal inventory rotation practices so older stock is used first across recurring fulfillment programs.
Storage note:
poly courier bags, poly bubble mailers,
and kraft bubble mailers should be stored
in clean, dry warehouse conditions.
Avoid unnecessary compression or damage to cartons,
particularly for padded mailers where interior cushioning
should remain in good condition prior to shipment.

Frequently Asked Questions
Poly Mailers FAQ
Common questions about poly mailer availability, sizes, mailer formats, custom printing, bulk quantities, and commercial shipping programs.
Do you stock poly mailers?
Yes. KL Rubber supplies standard poly courier bags, poly bubble mailers, and kraft bubble mailers in multiple commercial sizes. Bulk carton quantities are available for e-commerce fulfillment, warehouses, distributors, retail shipping, courier operations, and recurring commercial programs.
What poly mailer sizes are available?
KL Rubber offers multiple standard mailer dimensions across poly courier, poly bubble, and kraft bubble formats. Available dimensions and carton quantities vary by item. Review the Poly Mailer Size Chart for current standard size references.
What is the difference between a poly courier bag and a bubble mailer?
Standard poly courier bags are lightweight mailers suited to apparel, textiles, soft goods, and other non-fragile shipments that do not require cushioning. Poly bubble and kraft bubble mailers include internal cushioning for products that benefit from additional protection during transit.
Do you offer custom-printed poly mailers?
Yes. KL Rubber can supply custom poly mailers with printing for logos, branding, product information, promotional graphics, and private-label shipping programs. Custom dimensions, thicknesses, colors, and packaging requirements can also be reviewed depending on the commercial program.
What is the typical lead time for custom poly mailers?
Typical custom poly mailer lead times are approximately 8–12 weeks. Timing can vary depending on order volume, printing requirements, product specifications, production scheduling, and transportation requirements. KL Rubber can confirm expected timing when reviewing the specific custom program.
How do I choose the right poly mailer for my product?
Start with the dimensions and thickness of the product, then consider the level of protection required. Standard poly courier bags are appropriate for many lightweight and non-fragile shipments, while bubble mailers provide additional cushioning. For padded formats, compare the inside dimensions in the size chart to ensure adequate usable space.
