Precision in technical specifications is paramount when sourcing transparent anti-fog shrink film. The data reveals a wide spectrum of thickness options, ranging from twelve point five to fifty microns for PVC and twelve to fifty microns for PE. Some specific product models list thicknesses as narrow as 0.07mm or ranges like 10mic to 40mic. These variations directly influence the film's shrinkage behavior and sealing performance.

The width specifications are equally critical, with observed ranges extending from eight to one hundred and twenty inches, or more specific dimensions like 20-90cm. Length is typically customized on demand, allowing for flexibility in roll sizes to match production line speeds. The shrinkage rate, observed between fifty percent and sixty percent, dictates how tightly the film will conform to the product shape. Buyers must ensure that the selected film's shrinkage rate aligns with the thermal profile of their shrink tunnels to prevent distortion or film breakage.

Optical properties are another key consideration. The data mentions customizable high-clarity films and specific transparency levels. For anti-fog performance, buyers should look for films that maintain clarity in humid environments. The standard thicknesses for certain models are listed as 1.2, 1.5, 1.9, 2.5, 3.0, 3.5, and 3.8 microns, though these may refer to specific coating layers or standard gauges rather than the bulk film thickness. Heat sealing temperature is adjustable according to thickness, meaning that the supplier must provide precise thermal profiles for the specific gauge ordered.

Compliance, Environmental Attributes, and Safety

Environmental compliance and safety certifications are increasingly vital in modern procurement. The supply data highlights the availability of customizable eco-friendly attributes, including degradable PVC, PE, and POF films. This suggests that suppliers can tailor formulations to meet specific regulatory requirements or corporate sustainability goals. However, buyers must verify the specific nature of these "degradable" claims, as the term can encompass various mechanisms such as oxo-degradation or hydrolysis.

Anti-static performance is another compliance-related feature, with data indicating that anti-static PVC, PE, and POF films are available. This is essential for packaging electronic components or sensitive hardware where static discharge could cause damage. The data also notes features like moisture proof and water-soluble capabilities, which may be relevant for specific industrial or agricultural applications.

The usage data explicitly lists "Food & Medicine Film" as a primary application, implying that the material must meet relevant safety regulations. While specific certification names are not provided in the data, the presence of these usage categories necessitates a rigorous verification process to ensure the film is safe for direct or indirect food contact.

Cost Drivers and Economic Considerations

Understanding the cost drivers of shrink film is essential for budgeting and negotiation. The observed price range in the market spans from 0.1 to 150 USD, reflecting the vast differences in material quality, thickness, width, and customization levels. The Minimum Order Quantity (MOQ) ranges from 1 to 30,000 units, indicating that buyers can source small trial batches or large industrial volumes.

Key factors influencing cost include the polymer type, with POF and specialized PVC often commanding different price points than standard PE. Customization is a significant cost driver; attributes such as single-sheet folded tubular specifications, customized weight, and specific printing technologies add to the base material cost. The data confirms that printing technology and weight are customizable on demand, which allows for branding but increases production complexity.

Thickness is a direct cost factor; thicker films require more raw material and energy to extrude. Similarly, the width of the film affects the yield per roll. Buyers should analyze the total cost of ownership, considering not just the unit price but also the efficiency of the film on their packaging lines. A film with a higher shrinkage rate might reduce material usage, offsetting a higher per-unit cost.

Supplier Evaluation and Origin Verification

Selecting the right supplier requires a thorough evaluation of their capabilities and geographic origin. The data identifies Shandong and China as production origins, providing a geographical context for the supply chain. Buyers should verify the supplier's location to assess logistics costs and lead times. The product origin is a critical piece of information for importers managing supply chain risks.

Supplier evaluation should focus on their ability to meet the specific customization requirements observed in the data. Capabilities such as single-sheet folded tubular production, adjustable heat sealing temperatures, and customizable anti-static features indicate a supplier with advanced extrusion and coating technologies. The availability of multiple extrusion processes suggests a capacity for complex multi-layer films, which often offer superior performance.

Buyers must also assess the supplier's quality control systems. The data mentions specific product models like jybz5001, jybz2001, and SANRUN-250090401, which serve as identifiers for specific product lines. Verifying that the supplier can consistently produce these models with the specified tolerances is crucial. The packing method, listed as pallet or carton, should also be evaluated to ensure the film arrives without damage or contamination.
