Product advantages:
environment protection
Environmental impact during production process:
The carbon emissions of biodegradable wrapping film in the production process are significantly lower than those of traditional PE material wrapping film. Promoting the use of biodegradable wrapping film can reduce the global greenhouse effect and climate change impact. In addition, the material source of biodegradable wrapping film in the production process is mainly renewable resources. Compared with the production of traditional PE material wrapping film based on non renewable petroleum resources, it reduces the dependence on limited resources. Therefore, choosing biodegradable wrapping film is more in line with the current global trend of carbon reduction and low-carbon economy.
Environmental impact after disposal:
Biodegradable wrapping film can be fully stored for up to 18 months under normal use. After use, it can be completely degraded by microorganisms into water, carbon dioxide, and biomass in a specific natural environment, and ultimately converted into organic fertilizer to supplement the soil's nutrients. Discarding it in a microbial environment only takes 6 months to fully degrade, while traditional PE material wrapping film is usually difficult to degrade for hundreds of years after use. Therefore, choosing biodegradable wrapping film can reduce the long-term burden on the natural ecology.
safety
Non toxic and harmless:
The material of biodegradable wrapping film itself is green and environmentally friendly, and will not release any harmful substances when in contact with sensitive items such as food, beverages, and medicine, ensuring the safety of the product and the health of consumers.
Meets industry requirements:
The pharmaceutical, food and other industries have strict requirements for the safety of packaging materials. Biodegradable wrap film has become an ideal choice for these industries due to its green and environmentally friendly characteristics, and has significant advantages in compliance in related industries.
Performance advantages
viscosity:
The performance of biodegradable wrapping film in terms of viscosity is particularly outstanding. With a special thickening formula, the viscosity can be adjusted within the range of 5.9-6.8N, which is higher than the traditional PE wrapping film with a viscosity of about 1.98N. Higher viscosity can tightly wrap around items, preventing them from scattering or collapsing during transportation. Compared to PE wrapping film, it is less likely to fall off, overall improving packaging efficiency. In the long run, it can reduce usage losses during the packaging process.
Elastic recovery performance:
The molecular arrangement of biodegradable wrapping film is more regular than that of PE material, resulting in higher toughness and excellent elastic recovery performance, reaching 70%, surpassing traditional PE wrapping film with an elastic recovery performance of usually 50%. The higher elastic recovery performance makes the wrapping film less prone to deformation during bumps and movements, thus tightly wrapping the item and ensuring that it is not damaged during transportation. In the long run, it can reduce the loss of products during packaging.
Material strength:
The molecular arrangement of film raw materials is more regular than that of PE materials, resulting in higher material strength, with a transverse strength exceeding 15Mpa and a longitudinal strength exceeding 20Mpa. In contrast, the strength of traditional PE material wrapped films is about 12Mpa in the transverse direction and 17-18Mpa in the longitudinal direction. Higher strength is less prone to film breakage during use, and the biodegradable wrapping film has a film breakage rate of less than 10% per 15kg used, compared to the traditional PE material wrapping film which has a film breakage rate of around 20% per 15kg used, showing significant advantages. The lower breakage rate reduces the number of repeated entanglements after breakage, and long-term use can save overall usage.
