Overview
300 μm film is a versatile thin plastic material widely used in industrial and commercial applications. Its thickness of 300 micrometers (0.3 mm) balances flexibility and durability, making it suitable for protective layers, packaging, and insulation. Common materials include polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET), each offering distinct properties like chemical resistance or clarity. The film is manufactured through extrusion or calendering processes, ensuring uniform thickness and consistency.
Physical and Chemical Properties
The film's properties depend on its polymer base. For instance, LDPE films are soft and flexible, while PET films offer higher tensile strength and thermal stability. Typical density ranges from 0.92 g/cm³ (LDPE) to 1.40 g/cm³ (PET). Chemically, 300 μm films resist water, acids, and alkalis but may degrade under prolonged UV exposure or extreme temperatures. Their melting points vary: LDPE melts at ~120°C, whereas PET withstands up to ~160°C. Solubility is negligible in water or common solvents.
Main Applications
In packaging, 300 μm films protect goods from moisture and mechanical damage, often used for food wraps or industrial product covers. They also serve as dielectric insulation in electronics or barriers in construction. Specialized variants, like anti-static or UV-stabilized films, cater to niche sectors such as solar panel laminates or medical device packaging. Their adaptability makes them a staple in B2B supply chains.
Safety and Storage
Most 300 μm films are non-toxic and compliant with food-contact regulations (e.g., FDA-approved grades). However, overheating during processing can release fumes, requiring ventilation. Store rolls horizontally in a cool, dry environment to prevent deformation or static buildup. Avoid direct sunlight to maintain optical clarity and mechanical integrity over time.
B2B Procurement Guide
Buyers should specify material type, thickness tolerance (±10% is standard), and roll dimensions (width, length). Custom coatings or additives (e.g., slip agents) may incur higher costs. Bulk orders (e.g., >1,000 sqm) often reduce unit prices. Verify supplier certifications (ISO, REACH) for quality assurance. Sample testing is recommended to confirm suitability for end-use conditions.
