Why is polyolefin shrink film the preferred material in the packaging field? ​

As a biaxially stretched heat shrinkable film, polyolefin shrink film undergoes a special biaxial stretching process during the production process, which makes the molecular structure orderly arranged, thus giving the film excellent mechanical properties. During the packaging process, it can show stable and balanced shrinkage performance, and can fit tightly to any shape of product, avoiding wrinkles or looseness of packaging caused by uneven shrinkage. Its soft corner design also effectively solves the problem that traditional packaging materials are easy to scratch products or cause transportation wear, providing all-round protection for products. ​In essence, polyolefin shrink film has multiple characteristics such as toughness, cold resistance, and softness. In low temperature environment, its physical properties will not be significantly attenuated, and it can adapt to the storage and transportation needs of different regions and seasons. During use, no harmful gases will be released, which fully meets the strict safety requirements of food packaging and other fields, and eliminates the risk of secondary contamination of products from the source. ​

Performance upgrade and technological breakthrough of polyolefin shrink film ​
Polyolefin shrink film is continuously upgrading its performance, and the newly launched ultra-thin biaxially stretched heat shrinkable film is a typical representative of technological breakthroughs. On the basis of maintaining the original advantages of the material, the new film further improves the tensile strength and transparency by optimizing the formula and production process. This upgrade is reflected in the appearance and goes deeper into the core level of packaging function. In terms of packaging effect, the haze of the new polyolefin shrink film is significantly reduced, which means that the light transmittance is higher, which can make the products in the package present a clearer visual effect and enhance the display appeal of the product. The reasonable regulation of its oxygen permeability not only avoids product deterioration caused by excessive sealing, but also provides an ideal storage environment for goods that require appropriate air permeability, effectively extending the shelf life of the product. This precise optimization of performance allows it to further broaden the application boundaries while maintaining its economical characteristics, and can better meet the personalized needs of different industries for packaging materials. ​

Expansion of applicable scenarios of polyolefin shrink film
The wide applicability of polyolefin shrink film stems from its compatibility with different packaging equipment. Whether it is a traditional semi-automatic shrink machine or an efficient fully automatic shrink machine, it can be stably adapted without complex equipment debugging or parameter adjustment. This flexible adaptation capability reduces the equipment investment cost of the enterprise and improves the operating efficiency of the packaging production line. ​From the current market application, polyolefin shrink film has become the mainstream packaging material in many fields. In the food industry, it is often used for individual or collective packaging of products such as milk tea, instant noodles, and chocolate, which can not only highlight the appearance and texture of the product, but also ensure the freshness of the food; in the gift industry, its high transparency makes the gift box packaging more upscale, and its soft texture can avoid wear on the surface of the gift box; in the fields of daily necessities and stationery, it has also won wide recognition with its reliable protection performance and beautiful packaging effect. This cross-industry application coverage fully reflects its powerful functional adaptability. ​

Thickness specifications and selection logic of polyolefin shrink film ​
The thickness selection of polyolefin shrink film is based on specific packaging requirements, and films of different thicknesses have different focuses on performance. Thinner specifications can further reduce material consumption while maintaining good tensile strength, which is in line with the development trend of green packaging; while slightly thicker specifications have more advantages in puncture resistance and load-bearing capacity, and are suitable for products with higher requirements for protection performance. ​Manufacturers will provide polyolefin shrink films of various thicknesses according to market demand to meet different scenarios from light small items to medium-sized collective packaging. In the selection process, companies need to comprehensively consider the weight, shape, storage environment and characteristics of the packaging equipment of the product, and achieve the best balance between packaging effect and cost control by reasonably matching thickness specifications. This flexible thickness selection mechanism enables polyolefin shrink films to maintain a high degree of adaptability in diverse packaging needs, further consolidating its competitiveness in the packaging materials market. ​
