Seamless high frequency welding (molecular bond). Waterproof rating: submersion 1m\/30sec. Abrasion resistance: high (tarpaulin grade). Tear strength: reinforced with polyester mesh (\"steel in concrete\"). 210D Nylon: ~150g for 10L. Stitched seams with tape sealing. Waterproof rating: splash-proof only, tape degrades over time. Abrasion resistance: moderate. Tear strength: lower without coating. For kayaking where bag may drag on rocks, 500D PVC lasts longer. For ultralight backpacking, nylon saves weight but risk of seam leakage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHigh Frequency Welding vs. Heat Sealing vs. Stitching\u003c\/strong\u003e\u003cbr\u003e\nHigh frequency welding: Uses RF energy (27.12 MHz) to fuse PVC at molecular level. No adhesive. Weld strength equals parent material. Heat sealing: Uses heated bar (150-200°C) to melt PVC. Lower consistency, risk of burn-through. Stitching with seam tape: Needle holes create leakage points; tape peels after 1-2 years. This bag uses high frequency welding on all main seams, plus double layer sewing only on strap attachments (non-wetted area).\u003c\/p\u003e\n\n\u003ch2\u003eMulti-Scenario Buyer Applications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eKayaking Tour Operator – Client Gear Storage\u003c\/strong\u003e\u003cbr\u003e\nA kayak rental company on Lake Tahoe needed 200 dry bags to keep client phones, wallets, and change of clothes dry during 3-hour paddling tours. They previously used cheap vinyl bags that leaked after 20 uses. They selected 10L and 15L 500D PVC bags with high frequency welded seams. The bags are submerged daily — operator tested each bag by filling with air and dunking. Zero failure after 6 months. The roll-top closure with heavy duty buckle is easy for customers to use. The double-sided PVC with polyester mesh inter-layer resisted abrasion from sandy kayak cockpits. Reorder: 300 pieces the next season with custom printed logo.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCamping Club Merchandise Coordinator – Branded Gear for Members\u003c\/strong\u003e\u003cbr\u003e\nA national camping club with 500 members wanted a branded dry bag as part of the annual membership kit. They needed a durable bag that could be rolled up small in a backpack but hold a change of clothes and sleeping bag liner. The 5L and 10L sizes were selected. Custom screen printing applied the club logo in two Pantone colors. The high density nylon strap and heavy duty buckle withstand years of use. Each bag was individually packed in an OPP bag for presentation. MOQ was flexible — club ordered 300 units initially. Members reported the bag worked well for weekend camping trips. Reorder at 450 units the following year.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCorporate Event Planner – Beach Day Swag for 150 Employees\u003c\/strong\u003e\u003cbr\u003e\nA tech company held a summer beach day for 150 employees and wanted a useful giveaway. They chose 5L waterproof dry bags with the company logo printed in bright blue. The bags were folded into their own pocket size (single package reference 30x12x3 cm) and packed into gift boxes. Employees used them to protect phones and keys while swimming. The high frequency welded seams ensured no leaks when bags were tossed in the ocean. The roll-top closure with buckle was intuitive. Total order: 150 pieces delivered in 18 days. The HR manager reordered 200 pieces for next year's event plus 50 for new employee onboarding kits.\u003c\/p\u003e\n\n\u003ch2\u003eFAQ Matrix\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCustom Production:\u003c\/strong\u003e Can you print a full-color photo on the PVC dry bag?\u003cbr\u003e\nNo. The recommended method is screen printing with up to 4 Pantone spot colors. PVC material is not compatible with sublimation. For photo-quality, heat transfer is possible but less durable (may peel after 20 uses). Screen printed logos on 500D PVC last 2-3 years in outdoor use. Provide vector artwork with Pantone codes. Minimum line thickness 1.5mm. For complex multi-color logos, we can reduce colors or discuss alternatives.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLogistics \u0026amp; Shipping:\u003c\/strong\u003e What is the most economical way to ship 500 pieces of mixed 5L,10L,20L to Seattle?\u003cbr\u003e\nBased on carton data: 5L: 50 pcs\/carton, carton 45x35x30cm, 15kg. 10L: 50 pcs\/carton, 45x35x30cm, 15.7kg. 20L: 30 pcs\/carton, 40x35x30cm, 13kg. For 500 pieces mixed, total volume approx 10-12 cartons = 0.8-1.0 CBM. Sea freight LCL minimum 2 CBM, so you would pay for 2 CBM even if using less. To optimize, combine order with other products or increase quantity to 1000 pieces (2 CBM). Express air for 500 pieces (cartons weight ~150kg) costs $600-900 and takes 4-6 days. Sea freight at 2 CBM costs $200-300 plus customs clearance. Request a freight quote with your exact size mix.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePayment \u0026amp; Terms:\u003c\/strong\u003e Do you offer payment against shipping documents for a 1000-piece order?\u003cbr\u003e\nYes, for orders above $5,000. Standard T\/T: 30% deposit, 70% against scanned copy of bill of lading (sea freight) or airway bill (express). For first-time buyers, we require 50% deposit. For repeat corporate accounts with purchase order history, net 30 available after credit check. We accept L\/C at sight for orders above $10,000. Sample orders require full payment upfront via PayPal or credit card.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQuality \u0026amp; Compliance:\u003c\/strong\u003e How do you ensure the high frequency weld doesn't fail after repeated use?\u003cbr\u003e\nWe perform a destructive peel test on 2% of each batch: a 5cm weld sample is pulled in a tensiometer — minimum break force 200N. Weld thickness is measured to ensure complete fusion (target 0.8-1.0mm after welding). Each bag is air-inflated and submerged for 30 seconds at 1m depth. For orders above 500 pieces, we provide a video of 10 random bags passing the submersion test. The high frequency process creates a molecular bond that is actually stronger than the surrounding PVC — failure occurs outside the weld, never at the seam.\u003c\/p\u003e\n\u003cbutton class=\"header-cta-btn header-cta-btn--quote\" type=\"button\" data-open-header-quote\u003eGet a Quote\u003c\/button\u003e","brand":"SupplyBatch","offers":[{"title":"Option","offer_id":48421531353245,"sku":"60636363061","price":1.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/1354\/3325\/files\/HTB1jCU_QpXXXXXfXVXXq6xXFXXX0.webp?v=1781326217","url":"https:\/\/www.supplybatch.com\/products\/custom-500d-pvc-waterproof-dry-bag-2l-to-30l-high-frequency-welded-submersion-tested","provider":"SupplyBatch","version":"1.0","type":"link"}
