Certified industrial copper foils, double-sided acrylic tapes, and thermal management consumables directly manufactured from our cleanroom production facilities in Guangdong.
Gastropod mollusks such as snails and terrestrial slugs rely on moist, mucus-coated foot tissue for locomotion. When mucus touches copper, an immediate micro-galvanic current shocks their nervous system without killing beneficial garden flora or requiring synthetic pesticides.
Gastropod slime consists of water, glycoproteins, and electrolytes. Upon contact with electrolytic copper (≥99.95% Cu), a natural oxidation-reduction reaction generates a harmless yet repellent electric charge (50–120 mV) that causes instantaneous reflex withdrawal.
Unlike metaldehyde pellets, methiocarb, or chemical slug pellets that pollute waterways and poison domestic pets or birds, pure copper foil barrier tape offers 100% organic, non-toxic, and non-polluting mechanical-electrolytic pest exclusion.
Because Huayuan synthesizes both single-conductive and dual-conductive acrylic pressure-sensitive adhesives, our copper foil tape doubles as an industrial EMI/RFI shield, guitar cavity protector, and high-precision stained glass soldering foil.

Accelerated by the European Green Deal and North American organic farming standards, commercial agriculture and horticulture distributors are replacing toxic molluscicides with long-life metal physical barriers.
Home improvement chains and hypermarkets in the UK, Germany, and the US demand customized retail packaging, barcode tagging, blister cards, and specific roll lengths (4m, 10m, 20m) with customized high-tack paper backing.
High-tech vertical farms and organic strawberry/lettuce greenhouses procure 50mm-wide rolls in bulk jumbo sizes to seal aluminum frame perimeters, ensuring year-round crop safety without pesticide testing residues.
Because pure copper tape is inherently anti-slug and electromagnetic-conductive, hardware distributors procure dual-certified SKUs that can serve both electrical technicians (grounding/EMI) and homeowners.
Founded in 2007 with dual production facilities in Nanping High-Tech Park (Zhuhai) and Tanzhou (Zhongshan), Huayuan delivers unmatched precision and cost efficiency to overseas B2B brand owners.
Advanced reverse-roll micro-gravure coating eliminates bubbling, adhesive voiding, and pinholes, ensuring 100% full-surface conductivity and moisture resistance outdoors.
Equipped with imported high-speed rotary slitters, providing width precision to ±0.2 mm from 3 mm to 1200 mm, wound onto durable 1-inch or 3-inch plastic/cardboard cores.
Immediate container drayage to Shenzhen, Hong Kong, and Guangzhou ports. Rapid LCL/FCL ocean dispatches, complete with EUR1/Form A certificates and bonded warehouse storage.
Stringent raw material copper ingot spectral analysis, 180-degree peel testing, holding power analysis, and humidity chamber aging ensuring zero delamination outdoors.

Ensure 100% repellent efficacy by adhering strictly to recommended barrier geometries and surface prep guidelines across commercial and domestic environments.
Applied as a continuous perimeter ring around terracotta pots, wooden planter boxes, greenhouse tables, and nursery tubs. Crucial: Maintain at least a 25mm to 30mm tape width so larger slugs cannot bridge the barrier without sustained body contact.
Seals irrigation benches, automated hydroponic nutrient channels, and climate control pipe penetrations, preventing gastropod infiltration into high-value seedbeds and organic crops without chemical pesticide residues.
Beyond garden pest exclusion, our thin-gauge electrolytic copper foil with conductive adhesive serves stained glass crafters (the Tiffany method), offering ultra-smooth lay-down, crisp foil edges, and flawless solder wetting.
Direct engineering answers for commercial purchasers, retail brand buyers, and agricultural operations directors.
No. While copper develops a natural brownish-green patina (copper oxide/carbonate) when exposed to air and rain, its surface electrochemical reactivity with gastropod slime remains active. A quick gentle rub with fine steel wool or citric acid restores shiny copper aesthetics if desired, but repellent shocking action persists regardless.
We strongly recommend a minimum width of 25mm to 30mm (approx. 1 to 1.25 inches). Narrower tapes (such as 5mm or 10mm) allow large adult slugs (like Arion vulgaris) to arch their bodies over the strip without sufficient slime contact, bypassing the galvanic deterrent. For maximum defense, two parallel rows spaced 10mm apart provide absolute closure.
Non-conductive adhesive coats only the copper carrier with standard acrylic glue; current flows only along the top copper surface. Conductive adhesive is formulated with microscopic metallic particles, enabling electrical conductivity through both the carrier and the adhesive layer. Conductive backing is essential when splicing tape segments together or using it for electrical grounding and EMI shielding.
Yes. Huayuan provides complete turnkey OEM/ODM packaging services. This includes custom retail blister packs, shrink wrapping with printed color insert cards, roll printing, custom die-cut inner core labels, retail display boxes (PDQ), and Amazon FBA-compliant barcoding dispatched from our Zhuhai production hub.
Our outdoor formulation employs cross-linked solvent acrylic pressure-sensitive adhesive tested for 1,000+ hours under QUV accelerated weather testing. It resists moisture emulsification, frost brittle fracture down to -20°C, and thermal softening up to +120°C on clean wood, plastic, ceramic, glazed pottery, and metal surfaces.
