PVC transparent wrapping film When choosing a suitable transparent PE wrapping film, in addition to considering the packaging items, usage scenarios, and viscosity requirements, you also need to consider the specifications and quality of the wrapping film:
Consider the packaging items
Industrial packaging cling film PVC transparent wrapping film Weight and size: Large and heavy goods, such as stone and mechanical equipment, require thick and high tensile strength wrapping films, such as products with a thickness of more than 200μm and a tensile strength of more than 50MPa, to ensure that they can withstand the weight of the goods and provide stable packaging; small and light items, such as stationery and small accessories, can choose 80-120μm thick wrapping films, which are light and low cost.
PVC transparent wrapping film Shape and texture: For items with regular shapes, such as cartons, the requirements for the fit of the wrapping film are low, and a wrapping film with ordinary tensile properties is sufficient; for items with irregular shapes or uneven surfaces, such as pipes and balls, highly flexible and self-adhesive wrapping films are required for tight fit. Items with smooth surfaces, such as glass products, should be prevented from slipping by using high-viscosity wrapping film; items with rough surfaces, such as woven bags, have relatively low requirements for viscosity, but require wrapping film with good puncture resistance to prevent puncture.
Consider usage scenarios
PE large roll packaging film Storage environment: In a humid environment, such as a warehouse near a water source or with high humidity, you need to choose a wrapping film with good moisture-proof performance, which can be achieved by adding moisture-proof additives; in a high-temperature environment, such as open-air storage or near a heat source, you should choose a high-temperature resistant wrapping film with a melting point above 120°C to prevent the wrapping film from deforming and melting.
Industrial packaging cling film PE large roll packaging film Mode of transportation: Long-distance transportation has high vibration and collision risks, so you should choose a wrapping film with strong tear and puncture resistance; short-distance transportation or local delivery requires relatively low strength requirements for the wrapping film, but it still requires certain stretching and retraction properties to ensure that the goods are not loose during transportation.
Consider the viscosity requirements
Industrial packaging cling film PE large roll packaging film High viscosity, medium viscosity and low viscosity: Items that need to be tightly fixed and not easy to slide, such as stacked metal sheets, are suitable for high viscosity wrapping film, and the initial viscosity can reach more than 10N/25mm; for general cargo packaging, such as daily necessities and food, the initial viscosity of medium viscosity wrapping film is 5-8N/25mm to meet the needs; for items that are easily contaminated by viscosity, such as some electronic products, low viscosity wrapping film should be selected, and the initial viscosity is less than 3N/25mm.
