Material
We manufacture from virgin-grade TPU for eco-positioned beauty lines or cost-optimized PVC for promotional programs. TPU maintains 90%+ light transmission after extended use without cold-cracking; PVC options use calcium-zinc stabilizers meeting EU standards. Both materials are BPA-free, phthalate-free, and REACH/Prop 65 compliant with batch-level documentation available on request.

Description
Transparent pouches are constructed with 8kW high-frequency welding at 27.12MHz—creating molecular bonds stronger than stitched seams. Zippers are ultrasonically welded to the bag body preserving waterproof integrity. Each unit passes backlight pinhole inspection and 50-cycle zipper torture testing before tissue-wrap packaging for surface protection during transit.
Use For
  • TSA-compliant travel pouches for airline and duty-free retail.
  • Gift-with-purchase clear bags for skincare and cosmetics launches.
  • Promotional transparent pouches for beauty and wellness campaigns.
  • Retail collections requiring visible product display through packaging.
Key Features
  • RF-Welded Leak-Proof Seams: Molecular fusion replaces stitching for waterproof, tear-resistant bonds.
  • TPU Clarity Retention: Premium TPU resists yellowing far longer than commodity PVC alternatives.
  • Multi-Method Branding: Silk-screen, UV print, foil stamp, emboss, or custom metal puller tags.
  • Compliance Ready: REACH, Prop 65, and odor-free certification documentation supplied per batch.

Why Transparent Formats Sell

Transparent pouches are the default for security screening, event bag checks and stadium entry - buyers choose them for fast inspection without opening. On the retail side, clear TPU shows the product inside, which lifts perceived value for travel kits and gifting programs. The trade-off buyers weigh is TPU (softer, more eco-friendly perception) versus PVC (stiffer, lower cost) - the right call depends on target market and retail price point.

Manufacturing Notes for RF-Welded Clear Bags

The critical process is high-frequency RF welding: the film seam must be fused evenly so the pouch holds liquids without leaking while staying flexible. Film thickness and welding temperature interact - too thin welds tear at the seam, too thick film makes the bag stiff and prone to cracking along fold lines. The nylon zipper is heat-sealed into the film, so zipper tape quality and the seal position are the two spots a sample inspection should focus on.

Sourcing Checklist

In your tech pack specify film thickness, transparency level, and whether the bag needs to pass airline liquid restrictions. Mark logo placement away from weld seams - printing across a weld line distorts. Confirm Pantone for zipper pulls and trim, and state whether you need a hang tag or retail-ready card. Request a sealed-weld sample and test it with water before approving bulk.

Product FAQ

Technical details for procurement teams

What is the main difference between TPU and PVC for cosmetic bags?

Direct Answer: TPU is the more sustainable, cold-flexible, non-yellowing option for eco-minded beauty brands, while PVC is more cost-effective for short promotional programs. Both are 100% waterproof and seam-welded by high-frequency equipment.

  • TPU Best For: sustainable brands, cold flexibility, non-yellowing
  • PVC Best For: cost-effective promotional runs
  • Waterproofing: 100% waterproof
  • Seam Method: high-frequency RF welding
TPU is eco-friendly, biodegradable, and remains soft in cold weather without yellowing over time—ideal for sustainable beauty brands. PVC is more cost-effective for promotional programs. Both are 100% waterproof and manufactured with high-frequency welding for leak-proof seams.
Are your clear bag materials compliant with REACH and California Prop 65?

Direct Answer: Yes. Our TPU and PVC are BPA-free and phthalate-free, meeting REACH and California Prop 65, and we supply REACH and Prop 65 compliance certificates on request. Materials are odorless and safe against cosmetics.

  • Safety Standards: REACH + California Prop 65
  • Material Exclusions: BPA-free, phthalate-free
  • Certificates: provided on request
  • Contact: mike@merrisbags.com
Yes. All TPU and PVC materials are BPA-free, phthalate-free, and meet strict international safety standards. We provide REACH and Prop 65 compliance certificates upon request. Materials are odorless and safe for direct contact with cosmetics and skincare products.
How do you ensure the seams will not tear or leak?

Direct Answer: Instead of stitching, we RF-weld the material for molecular bonds far stronger than thread, and every bag is pressure-tested before shipment. Across 12 years of production, seam failure stays below 0.2%.

  • Seam Method: high-frequency RF welding, no stitching
  • Pre-ship Test: pressure test per bag
  • Seam Failure Rate: below 0.2% over 12 years
We use high-frequency RF welding instead of stitching, creating molecular bonds significantly stronger than thread. Machines operate at precise frequencies with automated pressure feedback. Each bag undergoes pressure testing before shipment; seam failure rate is below 0.2% across 12 years of production.
