Product Description Cold Stretched Sleeve Film | Intelligent Packaging Solution Without HeatingCold stretched sleeve film, also known as cold shrink film, achieves tight packaging through elastic retraction without heating, simplifying processes and reducing energy consumption. It is the ideal choice for modern efficient packaging.Core AdvantagesHeat-Free Shrinkage:Triggers elastic retraction via mechanical stretching, avoiding damage to heat-sensitive products and suitable for diverse scenarios.High Elasticity & Strong Protection:Elastic recovery rate ≥90%, tensile strength ≥20MPa (longitudinal) and ≥15MPa (transverse), tightly wrapping to prevent abrasion and loosening.Energy-Saving & Efficient:No heating required, energy consumption reduced by 50%+ compared to heat shrink films. Supports manual/automated packaging for different production needs.Eco-Friendly Options:Offers conventional materials (PVC, polyolefin PE/PP) and eco-friendly films (degradable PBAT/PLA, recycled rPE/rPP).Key MaterialsMaterial TypeCharacteristics & AdvantagesTypical ApplicationsPolyvinyl Chloride (PVC)Low cost, good elasticityGeneral industrial packagingPolyethylene (PE)Flexible, low-temperature resistant, eco-friendlyFood and daily necessities packagingPolypropylene (PP)High strength, excellent weather resistanceOutdoor building materials, heavy-duty packagingBlended PolymersBalances elasticity and strengthComplex scenarios like cables and pipesDegradable Materials (PBAT/PLA)Environmentally degradableFood and medical packagingDiverse Application ScenariosIndustrial Field:Anti-winding for cables/wires, bundling for pipes/profiles, dust/moisture protection for mechanical parts.Consumer Sector:Clustering packaging for bottled daily goods, skin packaging for low-temperature foods.Special Scenarios:Sealing for chemical drums to prevent leakage, anti-aging protection for tiles/building materials in open storage.Packaging Process & Usage RecommendationsOperation Modes:Manual stretching or automated packaging via cold stretch sleeve machines, with efficiency up to 100 pieces/minute.Thickness Selection:50-80μm for light items, 100-200μm for heavy-duty items.Printing Support:Gravure/flexo printing with special inks to ensure clear, fade-resistant patterns.Storage Conditions:Store in a cool, dry place away from direct light and heavy pressure, shelf life 6-12 months.Innovations & UpgradesEnvironmental Innovation:Degradable materials applied in food and medical packaging to meet green trends.Functional Expansion:Antibacterial films for medical devices, conductive films for electronic component protection.Intelligent Production:AI visual inspection systems for real-time monitoring to ensure stable packaging quality. Characteristic Greentec 7/9-layer co-extrusion high-barrier filmline adopts specially designed screw barrel and mold, which can process resin materials such as PA and EVOH, so that film products have excel-lent gas barrier perfor-mance, it can effectively block the penetration of oxygen, nitrogen, carbon dioxide and water vapor, and meet the various needs of different users for preservation, air tightness, corrosion and mois- ture resistance. The machine is also equipped with automatic air ring, online thickness measuring system, weight-less feeding system, these auxiliary configurations can effectively improve the film production and thickness uniformity.Using linear variable temperature control technol-ogy, the temperature control precision of the cooling air inside the membrane bubble is improved, so as to effectively control the shrink-age of the film. With more intuitive visual operation.More optimized closed-loop control of the entire line. Product application The equipment can be used to produce cold and fresh barrier packaging, cooked food barrier packaging, medical barrier packaging, etc. Product ParametersModelMax Layflat film widthProduct thicknessLay structure Total powerMax CapacityGT-1500-7/9X1500mm0.03-0.12mmABCDEFG&ABCDEFG/H/I250-300kw300-400kw/hGT-1800-7/9X1800mm0.03-0.12mmABCDEFG&ABCDEFG/H/I300-350kw400-500kw/hGT-2200-7/9X2200mm0.03-0.12mmABCDEFG&ABCDEFG/H/I250-300kw500-600kw/hCertificationsAfter Sales ServiceCompany Profile
