Frequently Asked Questions
Is “Bester anti moldy bag” the same as your anti-mold chip or pouch?
Yes. “Bester anti moldy bag” is the official branded packaging series printed on our products, covering our advanced vapor-phase anti-mold solutions—including the A505 anti-mold chip and C304 anti-mold pouch. Unlike passive silica gel desiccants, they actively and continuously release powerful anti-mold factors inside sealed shoe boxes, creating a 360° protective atmosphere to inhibit mold growth effectively during transit and storage.
Which SKU should my factory use — A505 or C304?
Use A505 for peak-season suede/leather exports and long ocean transits. Use C304 for compact boxes, lighter materials, or when you need a precision-dosed, cost-effective anti moldy bag without sacrificing REACH compliance.
What certificates do brand auditors request?
Most AVL audits require SGS REACH SVHC screening (report No. CANAF26001423003; 251 SVHC substances + 4 potential SVHCs, all not detected ≤ 0.1% w/w), DMF-free verification (SGS report No. CANAF26001423001), product MSDS/SDS, and batch traceability. See our Testing & Compliance Center and Regulatory & Restricted Substances pages.
What is the difference between an anti mold chip and a silica gel desiccant?
An anti mold chip releases vapor-phase anti-fungal agents to inhibit mold growth inside sealed packaging — it does not absorb moisture. A silica gel desiccant only absorbs humidity passively and can saturate, losing protection. Bester A505/C304 chips are designed specifically as anti mold stickers for shoes, not as generic moisture absorbers.
