Waterproof Sticker Custom — PVC Foam Stickers for Bath, Umbrella, Bottle

Waterproof ≠ un-stuck: the waterproof logic of PVC foam stickers

"Waterproof stickers" on Alibaba actually come in three types: ① PVC printed stickers (thin, flat, lamination gives water resistance), ② PET waterproof labels (high water resistance, common on electronics), ③ PVC foam stickers (thick, 3D, PVC itself does not absorb water, and HF welding seals the edges completely). Yikang makes the third — water-resistant AND washable AND leaves no residue on removal.

Where PVC foam waterproof stickers actually fit

• Bathroom: tiles, mirrors, glass doors (humidity lifts ordinary stickers in days)
• Umbrella: outer and inner surfaces (rain dissolves ordinary stickers)
• Water bottles / tumblers: dishwasher-safe (PVC foam + HF welding)
• Swim rings / life vests / surfboards: prolonged water + UV (PVC is UV-resistant)

MOQ and pricing

MOQ 2,000 pcs per design. Standard PVC waterproof foam stickers run US$0.05-0.25/pc FOB Shenzhen (depending on size, thickness and volume). 30-60% pricier than flat PVC printed stickers, but they survive 6+ months of repeated washing — lower cost per use over time.

3 things to confirm before ordering

• Scene: bathroom vs umbrella vs bottle — adhesive strength differs (permanent / removable / high-tack)
• Food-contact: stickers on cup inner walls must confirm if FDA-grade material is needed (Yikang can switch material but flag it upfront)
• IPX7: long-submersion apps (pool signage) require buyer-side testing, Yikang does not issue waterproof-grade certificates

Yikang has been making waterproof PVC foam stickers for 8 years. The most common question: "Can it go in the dishwasher on a water bottle?" Answer: yes, 200+ cycles without edge lift, but exact count depends on your dishwasher temperature (we recommend below 70°C) and adhesive choice. Inquiries welcome.
