Overview
Toyobo CPP (Cast Polypropylene) is a high-performance thermoplastic film manufactured by Toyobo Co., Ltd., a leading Japanese chemical company. It is produced through a casting process that ensures uniform thickness and superior optical clarity. The film is widely recognized for its versatility in packaging and industrial applications due to its balance of mechanical strength, heat resistance, and barrier properties. Unlike oriented polypropylene (OPP), CPP retains its flexibility and is often used as a heat-sealable layer in composite films. Its production process allows for customization in terms of thickness, surface treatment, and additives to meet specific industry requirements.
Physical and Chemical Properties
Toyobo CPP exhibits a density of approximately 0.90–0.91 g/cm³, making it lightweight yet durable. Its melting point ranges between 160–170°C, which enables heat-sealing without compromising structural integrity. The film is chemically inert, resistant to acids, alkalis, and most organic solvents, ensuring stability in diverse environments. Key performance metrics include low moisture vapor transmission rates (MVTR) and excellent optical clarity with haze values typically below 5%. The film can be metallized or coated to enhance barrier properties against oxygen and UV light, extending its utility in sensitive applications like food and pharmaceutical packaging.
Main Applications
The primary use of Toyobo CPP is in flexible packaging, particularly for food products such as snacks, confectionery, and frozen goods. Its heat-sealing capability and resistance to grease make it ideal for laminates with PET or BOPP films. In the medical sector, CPP is employed in sterile packaging due to its compatibility with sterilization methods like gamma irradiation. Industrial applications include adhesive tapes, synthetic paper, and release liners. The film's printability allows for high-quality graphics in labels and promotional packaging. Specialty grades with anti-fog or anti-static additives cater to niche markets like agricultural films and electronic component wrapping.
Safety and Storage
Toyobo CPP is generally recognized as safe for food contact when compliant with FDA or EU regulations. However, processing at temperatures above 200°C may release volatile compounds, necessitating proper ventilation. The film is non-toxic but should not be incinerated due to potential hydrocarbon emissions. Storage recommendations include keeping rolls in their original packaging at temperatures below 35°C and relative humidity under 60%. Prolonged exposure to UV light or ozone can degrade mechanical properties, so indoor storage is preferred. For B2B buyers, batch-specific certificates of analysis (CoA) should be requested to verify compliance with industry standards.
B2B Procurement Guide
When sourcing Toyobo CPP, buyers should specify parameters such as thickness (commonly 20–100 microns), width, and surface treatment (e.g., corona discharge for improved adhesion). MOQs (Minimum Order Quantities) typically range from 1–5 metric tons, with lead times of 4–8 weeks for customized orders. Pricing depends on raw material fluctuations in the polypropylene market and order volume. For reference, standard-grade CPP films cost approximately $2–$5 per kg. Partnering with authorized distributors ensures access to technical support and consistent quality. Buyers should also evaluate supplier certifications like ISO 9001 and request samples for performance testing under real-world conditions.
