Import Black Pet Film 0.125mm — Buy in wholesale FOB from Supplier in China

Black PET film 0.125 mm is a biaxially oriented polyester film supplied by Li Jia Lin from Shenzhen, China, with a calibrated thickness of 125 micrometres. The material exhibits a density of 1.33 g/cm3, longitudinal and transverse tensile strength of 53 MPa in both directions, and elongation at break of 250% in both axes. Oxygen permeability is rated at 4 to 4.5 cm3, mm/(m2, 24h, 0.1 MPa), with moisture permeability below 3 g, mm/(m2, 24h). The maximum continuous operating temperature approaches 70 degrees Celsius. These parameters position the film within the standard performance envelope for biaxially oriented PET packaging and industrial grades.

The film is manufactured from polyethylene terephthalate resin, a thermoplastic polyester that can be recycled through mechanical reprocessing or energy recovery without generating halogenated combustion products. The black coloration is achieved through masterbatch addition of carbon black or organic pigments during extrusion, which also imparts partial light-blocking properties. Biaxial orientation during manufacture aligns polymer chains in both machine and transverse directions, yielding balanced mechanical properties and dimensional stability. The 0.125 mm thickness sits within the common range for thermoforming sheet, printed overlays, and separator films. Standard industry thickness tolerances for biaxial PET film of this gauge are typically plus or minus 5% or tighter, though the supplier's specific tolerance band should be confirmed directly.

Primary applications include vacuum-formed food packaging, toy and stationery blister packs, antistatic electronic component pouches, and general-purpose folding cartons and cards. The oxygen and moisture barrier properties, while moderate compared to metallised or multilayer structures, are sufficient for short-to-medium shelf-life goods. The 70 degrees Celsius upper limit restricts use in hot-fill or retort applications unless specifically stabilised. Buyers include packaging converters, electronics manufacturers, and printing houses. Li Jia Lin operates from Longhua District, Shenzhen, placing the supplier within the Pearl River Delta manufacturing cluster. Trade terms, minimum quantities, lead times, and certification status must be confirmed directly with the supplier, as these are not stated in available data.

Li Jia Lin is located at 1st Floor, Xiangheyuan Industrial Zone, Guanlan Street, Longhua District, Shenzhen, 518110, Guangdong Province, China. The address places the supplier within one of China's most concentrated flexible packaging and plastic film manufacturing regions, with access to PET resin suppliers, masterbatch compounders, and downstream converting equipment. The "1st Floor" designation suggests the operation occupies part of a multi-tenant industrial building rather than a standalone facility. The supplier holds a "harbor" trust tier. The response rate is recorded at 0.00% with average response hours of 0, indicating no platform-mediated response history is available.

The supplier profile does not state establishment year, registered capital, production capacity, number of employees, factory floor area, quality management certifications, or key account references. No information is provided about extrusion line width, annual tonnage output, or whether Li Jia Lin operates as a manufacturer, trader, or hybrid. The source description contains technical product information but no verifiable company credentials. Buyers should request business licence verification, ISO 9001 or ISO 14001 certificates if claimed, and factory audit access before committing to volume orders. Given Shenzhen's regulatory environment, also confirm compliance with local environmental permits for PET film manufacturing.
