When sourcing Micro Pak anti-mold stickers or PE sheets, the price is heavily influenced by the active ingredient concentration and material composition. Ensure the product uses food-grade, non-toxic materials that comply with global safety standards. Key technical factors include the moisture-activation mechanism, which ensures the anti-mold agents are only released when needed, and the shelf life, which should typically be 12 to 24 months if stored in original sealed packaging. Always verify the dimensions (e.g., 5cm x 2.5cm) and packaging units (rolls vs. sheets) as these directly impact the unit price.
