Applications
TF1007's primary application is the heat-seal layer in CPP (cast polypropylene) composite film structures. In a typical CPP laminate, TF1007 forms the innermost ply — the layer that contacts the product and bonds to itself or to a substrate under heat and pressure. The terpolymer composition provides the lower seal-initiation temperature that a standard homopolymer or binary copolymer cannot match, making TF1007 appropriate for lightweight, thin-gauge laminates where excessive dwell time or jaw temperature would damage the film structure.
Food packaging is the largest downstream market for CPP heat-seal film. Snack bags, candy wrappers, biscuit trays, and flexible pouches for dry and moist foods all rely on a reliable seal layer. TF1007's yellow index limit of ≤2.0 keeps the film optically neutral — important where the packaging must show the product clearly or carry accurate brand colors after printing. The Vicat softening point at ≤118°C positions TF1007 for ambient and moderate-temperature packaging rather than aggressive retort applications.
Cosmetics and personal care packaging represent a second major market. Sachets for skincare, sample pouches, and blister-backing films for tablet or capsule packaging all demand a seal layer that performs at relatively low temperatures without haze or contamination risk. TF1007's controlled pellet appearance specification — limiting colored granules to ≤5 pcs/kg — directly supports the contamination control requirements that cosmetic packaging converters operate under.
Garment and textile packaging is a third recognized application. Polybags and header bags for clothing often require a seal that is strong enough to survive logistics handling but opens cleanly at retail. TF1007's combination of adequate impact strength and moderate stiffness gives the finished bag functional integrity without brittleness.
Why Source Through BASTONE
BASTONE Petrochem distributes petrochemical resins from China's three major state-owned producers — SINOPEC, PetroChina, and CNOOC — under a structured distribution arrangement. TF1007, as a Dushanzi Petrochemical (PetroChina) product, sits within BASTONE's established supply channels. Buyers receive batch-traceable COA documentation tied to the Dushanzi production lot, covering MFR, mechanical properties, and appearance parameters specified in the manufacturer's provisional standard.
The parent BASTONE group operates an in-house R&D center with working chemists who understand polypropylene compounding and film processing. Grade selection support — choosing between TF1007 and related grades TF1005 or TF1007D based on film line configuration and end-use sealing requirements — is a practical service BASTONE provides before an order is placed, not a sales call with a brochure. Buyers sourcing multiple resin categories can also consolidate CPP-grade PP alongside other polymer and petrochemical requirements through a single export counterpart.
BASTONE's export operations run through Zhejiang Bastone Technology Co., Ltd, with 10+ years of documented export history supporting flexible trade terms, standard export documentation packages (COA, MSDS, packing list, B/L), and coordination on container loading from ports in East China.
