The cost of polyolefin (POF) shrink film is influenced by several key factors, and understanding these variables can help businesses make more informed decisions when selecting packaging materials.
One of the main factors is the type of material used in the production of the shrink film. Variants like high-density polyethylene (HDPE), low-density polyethylene (LDPE), and polypropylene (PP) may vary in cost based on their properties and applications. The choice of material directly affects the overall pricing.
Another significant factor is the level of transparency required for the film. High-clarity films, which offer enhanced visual appeal and product visibility, may require additional processing or the inclusion of specialized additives. These extra steps can contribute to a higher cost compared to standard films.
The size and format of the rolls also influence the cost. Larger rolls or custom packaging formats often involve different pricing structures, as they may require specialized equipment or adjustments in the manufacturing process.
Lastly, market conditions, including fluctuations in raw material prices and energy costs, can impact the overall cost of polyolefin shrink film. Changes in the prices of essential raw materials or energy used in production can lead to price variations, making it important for businesses to stay informed about the broader economic landscape.
Q: How durable is polyolefin?
A: The durability of polyolefin is excellent. It has the characteristics of low relative density, chemical resistance, water resistance, good mechanical strength and electrical insulation. At the same time, polyolefin has high hardness and excellent wear resistance and impact resistance, which makes polyolefin an ideal material for manufacturing lightweight and durable products.
Q: Is polyolefin food grade?
A: Polyolefin can be used for food-grade packaging materials, but it needs to meet certain production standards and safety requirements. Polyolefin is a plastic material made by polymerizing monomers such as propylene or ethylene, and has excellent physical and chemical properties, such as heat resistance, cold resistance, and chemical corrosion resistance. Internationally, the relevant production standards mainly include FDA, EU Food Safety Authority and China GB. These standards specify the physical, chemical, biological, toxicological and other requirements that polyolefin materials should meet when used in food contact, such as polyolefin materials should not contain harmful substances, will not affect food, and will not destroy the nutritional components of food. Therefore, if the polyolefin material meets these standards, it is food grade.
Q: Will polyolefin shrink during storage?
A: Polyolefin may shrink during storage, which mainly depends on its specific type and storage conditions. For example, some commercial polyolefin separators may show severe thermal shrinkage and low permeability due to inherent disadvantages such as low melting temperature and weak surface energy. However, by modifying the raw materials or blending, the shrinkage can be reduced to ensure the safety of the product. Therefore, when storing polyolefin, attention should be paid to its type and storage conditions to avoid unnecessary shrinkage.
Q: What is single roll polyolefin?
A: Single roll polyolefin generally refers to polyolefin materials provided in roll form. This material is made into a continuous film or sheet during the manufacturing process and then rolled up for easy storage and transportation. Single roll polyolefin can have various thicknesses and widths to meet different application requirements. It is often used in packaging, construction, agriculture and other fields as a protective, isolation or decorative material.
Q: How to choose the shrink wrap roll size?
A: When choosing the size of shrink wrap roll, you need to consider the following factors:
Size of the item being packaged: First, measure the length, width, and height of the item being packaged to ensure that the selected shrink wrap roll can completely cover the item and form a good protection.
Shrinkage ratio: Different shrink wrap materials have different shrinkage ratios. When choosing the size, you need to take this into account to ensure that the packaged items can achieve the desired tightness and appearance.
Type of packaging machine: If you use an automatic or semi-automatic shrink wrap machine, you need to make sure that the selected packaging roll size is compatible with the machine.
Economy: When choosing the size, you also need to consider the cost factor. A packaging roll that is too large may waste material, while a packaging roll that is too small may require frequent replacement, increasing labor costs.

How can polyolefin shrink film manufacturers improve the transparency and gloss of products by adjusting the production process?
In the polyolefin shrink film manufacturing industry, enhancing transparency and gloss is both a technical challenge and a crucial competitive edge. As a company committed to producing high-quality products, we understand the importance of these factors. To stay ahead in the market, we continuously refine our product line through precise adjustments and innovative processes, ensuring that we meet our customers' demands for both aesthetic appeal and superior performance.
Starting from the source, our company uses all imported high-quality raw materials, which is the cornerstone for improving product transparency and gloss. Imported raw materials tend to have a more stable molecular structure and fewer impurities, which is essential for the production of highly transparent and glossy POF shrink film. We strictly screen suppliers to ensure that each batch of raw materials meets high international standards, such as ISO, BRC and other certification requirements, which not only ensures the purity of the raw materials, but also provides a solid foundation for subsequent processing.
Biaxial stretching is the core step in the production of polyolefin (POF) shrink film, which directly affects the physical properties and appearance quality of the product. Our company has conducted in-depth research and optimization on this link:
Precise Temperature Control: During the biaxial stretching process, maintaining accurate control over heating and cooling temperatures is crucial. If the temperature is too high or too low, it can result in uneven molecular chain alignment, negatively impacting the film's transparency and gloss. To address this, we utilize an advanced temperature control system that ensures precise temperature adjustments within ±1°C. This level of accuracy optimizes the molecular chain orientation, leading to improved transparency and gloss in the final product.
Stretch Ratio and Speed Adjustment: The stretch ratio and speed are critical factors that influence the performance of the film. Through extensive testing and data analysis, we have identified the optimal combination of stretch ratio and speed that not only enhances the film’s strength but also significantly boosts its transparency and gloss. This fine-tuning is especially vital for ultra-thin products, such as 10-micron shrink film, where precise control is essential to achieve the desired quality.
Adding an appropriate amount of additives such as antioxidants and UV inhibitors to the raw materials can effectively improve the weather resistance and stability of POF shrink film, and also have a positive effect on its transparency and gloss. Our company has a professional R&D team, and through scientific proportions, it ensures that the additives can play a role without negatively affecting the transparency of the film. In addition, we also pay special attention to the environmental protection of additives, ensuring that all products meet food safety standards such as FDA, providing customers with a more secure choice.
Surface Treatment Technology plays a key role in enhancing the gloss of shrink film. By utilizing advanced corona treatment or plasma treatment technologies, we can micro-modify the surface of the film, increasing its surface energy and creating a smoother finish. This results in a more uniform light reflection, significantly improving the film’s gloss. This process is especially applied in the production of our JT01 polyolefin (POF) shrink film (10 microns), giving it a highly transparent and glossy appearance with enhanced visual appeal.
We have implemented a rigorous quality control system, monitoring every stage from raw material entry to final product delivery. Our production process is equipped with advanced testing tools, such as Fourier Transform Infrared Spectrometer (FTIR) and Scanning Electron Microscope (SEM), to continuously check product quality in real-time. We also gather customer feedback to improve and upgrade our products, ensuring our products stay ahead of industry trends.
Strong Production Capacity and Stable Supply Chain are key factors that support our ability to consistently provide high-quality shrink films. We maintain ample raw material reserves and operate efficient production lines, enabling us to respond quickly to market demands while stabilizing raw material prices. Additionally, our strict supplier management ensures consistent raw material quality, providing a reliable foundation for the continued enhancement of product transparency and gloss.
Through raw material selection, process optimization, scientific ratio of additives, surface treatment technology and strict quality control, Jtpackage has successfully improved the transparency and glossiness of POF shrink film, especially in JT01 polyolefin shrink film 10mic and other products. These efforts not only reflect our pursuit of technological innovation, but also our deep understanding and active response to customer needs.
