Poly Mailers

Find the answers you need below. If you have any additional questions, our customer service team is always here to support you.

Question 1: Which poly mailing bags are best for e-commerce shipping?
Poly mailing bags are ideal for e-commerce due to their lightweight construction, waterproof properties, and cost-effectiveness. For general textile and clothing shipments, PE mailing bags offer excellent tear resistance and moisture protection. For heavier or more sensitive products, we recommend coex mailing bags with multi-layer construction that provides superior durability. Our self-seal mailing bags feature a convenient peel-and-seal closure for fast processing, making them perfect for high-volume operations. All our poly mailers are compatible with DHL and other courier services, and with our fast shipping options, you can maintain an uninterrupted logistics chain for your business.

Question 2: What is the difference between Coex mailing bags and PE mailing bags?
Coex mailing bags (coextruded mailing bags) feature a multi-layer film construction that combines different plastic layers for enhanced strength and puncture resistance, making them ideal for heavier items or products requiring extra protection. PE mailing bags (polyethylene mailing bags) are made from a single-layer material, offering excellent tear resistance and waterproof properties at a more economical price point. Both types are weatherproof, dirt-resistant, and feature self-adhesive closures. Coex bags provide premium protection for valuable goods, while PE bags are perfect for lightweight textiles, documents, and standard e-commerce shipments. At karton.eu, both options are available in various sizes with immediate dispatch.

Question 3: Are poly mailing bags completely waterproof and weatherproof?
Yes, our poly mailing bags provide reliable waterproof and weatherproof protection for your shipments. The plastic film construction creates an effective moisture barrier that protects contents from rain, snow, and humidity during transit. Both our polyethylene and coextruded mailing bags are designed to be water-repellent and dirt-resistant, ensuring that textiles, documents, and other goods arrive in pristine condition regardless of weather conditions. The self-seal closure creates a secure, moisture-tight seal. This weatherproof protection makes poly mailers particularly valuable for outdoor delivery scenarios and long-distance European shipping, where packages may be exposed to various weather conditions.

Question 4: Can I use poly mailing bags for shipping clothing and textiles?
Absolutely! Poly mailing bags are exceptionally well-suited for shipping clothing and textiles. Our specialized poly bags for textiles protect garments from moisture, dirt, and damage during transit while remaining lightweight to minimize shipping costs. The tear-resistant, durable material ensures that even sharp edges or fasteners on clothing won't puncture the bag. Fashion retailers and textile businesses particularly appreciate the professional appearance and reliable protection our poly mailers provide. Available in various sizes from compact formats to spacious B4 mailing bags, you can find the perfect fit for individual garments or larger orders. We also offer custom printed mailing bags to showcase your brand professionally on every shipment.

Question 5: What sizes of poly mailing bags are available?
We offer a comprehensive range of poly mailing bag sizes to accommodate all shipping requirements. Our portfolio includes compact formats for small items like accessories or documents, medium sizes for standard clothing shipments, and spacious B4 mailing bags for larger parcels or multiple items. Each size is available as a self-adhesive mailing bag with peel-and-seal closure for convenient use. Whether you need poly envelopes for lightweight items or heavy-duty plastic postal bags for bulkier goods, our extensive selection ensures you'll find the optimal format. All sizes feature the same weatherproof, tear-resistant quality and are immediately available from stock with fast dispatch throughout Europe and complimentary standard shipping across mainland Germany.

Question 6: Do you offer bulk discounts and custom printed poly mailing bags?
Yes, we provide attractive volume discounts for poly mailing bags purchased in larger quantities, making us an ideal partner for B2B customers and high-volume shippers. Business customers also benefit from convenient invoice payment options. For professional branding, we offer custom printed mailing bags in single or two-colour printing, allowing you to showcase your company logo and brand identity on every shipment. This transforms standard poly mailers into effective marketing tools while maintaining all protective properties. Since 2007, we've been serving both B2B and B2C customers with premium-quality plastic mailing bags at competitive prices. Contact us to discuss your specific requirements for bulk orders or custom printing solutions.

Question 7: How do self-seal poly mailing bags work?
Self-seal poly mailing bags feature an integrated peel-and-seal closure that makes packaging fast, secure, and extremely convenient. Simply insert your items, remove the protective strip from the adhesive flap, and press firmly to create a strong, tamper-evident seal. This self-adhesive closure requires no additional tape, water, or heat, significantly speeding up your packing process and reducing material costs. The permanent adhesive ensures the bag remains securely closed throughout transit, while the sealed edge provides clear evidence of any tampering attempts. All our poly mailers and plastic shipping bags come with this practical closure system, combining ease of use with professional security for both business and private shipping needs.
