BOPP Heat Seal Film for Hardware Parts Packaging Clear Moisture Barrier 15-30μm
This BOPP heat seal film is intended for hardware parts packaging. Its high transparency allows quick identification of the appearance and specifications of screws, nuts, washers, and similar items. The base material is biaxially oriented polypropylene film with a heat seal layer, compatible with automatic packaging equipment. The film offers stable heat seal strength and good water vapor barrier properties, helping reduce the risk of moisture exposure for metal parts during storage and transport. It is suitable for individual or collective packaging of small hardware, electronic components, and various small metal parts.

Thickness is measured per ISO 4593:1993 (for unembossed film). Tensile properties follow ISO 527-3:2018. Heat seal strength is tested per ASTM F88. Optical properties (light transmittance, haze) follow ASTM D1003, and gloss per ASTM D2457. Water vapor transmission rate is determined by ISO 15106, surface tension by ISO 8296, heat shrinkage by ISO 11501, and density by ISO 1183.
