u003cpu003eGreen packaging material--Introduction to water-soluble plastic packaging filmu003cbr /u003eWater-soluble plastic packaging film is a novel green packaging material. The main raw material is polyvinyl alcohol with a low alcoholysis degree. It uses polyvinyl alcohol's film-forming properties, water solubility and degradability, and adds various additives, such as surfactants, plasticizers, and anti-sticking agents. Water-soluble film products are environmentally friendly packaging materials, and are recognized by the national environmental protection authorities in Europe, America, Japan and other countries. At present, biological oxygen demand (BOD) and chemical oxygen demand (COD) are mainly regarded as environmental protection indicators at home and abroad. The relevant Japanese authorities have determined that the biological oxygen consumption (BOD) of polyvinyl alcohol is much smaller than that of starch. After 5 days of biodegradation of Airvol's PVA products by Air Products, the measured BOD amount is less than 1% of the initial total BOD. Biological tests have proved that polyvinyl alcohol is neither toxic nor preventing the growth and reproduction of microorganisms, and has no effect on wastewater treatment and environmental sanitation. The relevant department's microbial decomposition test research also shows that polyvinyl alcohol is almost completely decomposed, which reduces COD very low. u003cbr /u003eAs far as the degradation mechanism is concerned, polyvinyl alcohol has both water and biological degradation characteristics. First, it dissolves in water to form a glue and penetrates into the soil, increasing the soil's mass adhesion, air permeability and water retention, and is especially suitable for sandy soil. Transformation. PVA in the soil can be decomposed by a strain of Pseudomonas, a bacteria isolated in the soil. The symbiosis system composed of at least two kinds of bacteria can degrade polyvinyl alcohol: one is the active bacteria of polyvinyl alcohol, and the other is the bacteria that produces the substances required by the active PVA bacteria. The oxidation reaction enzyme of the secondary alcohol catalyzes the polyvinyl alcohol, and then the hydrolase cuts the oxidized PVA main chain, further degrades, and finally degrades into CO2 and H2O. u003c/pu003eu003cbr /u003eu003c/pu003eu003c/pu003e

PET polyester universal film has excellent strength and dimensional stability, cold resistance and chemical stability, and is widely used in various substrates such as composite packaging, photosensitive film, metal evaporation, audio and video. Specifically, there are the following: 1. The main feature of semi-reinforced film is that it has high longitudinal tensile strength and is not easy to break under large tension. It is mainly used for packaging seals for boxed items. Commonly used standard thicknesses are 20μm, 28μm, 30μm, 36μm, 50μm, etc. 2. Bronzing film. The biggest feature is good tensile strength and transparency, stable thermal performance, and low binding force with certain resins. It is mainly suitable for small dimensional changes during high-temperature processing or as a transfer carrier. 3. Printing composite packaging film. The main features are good transparency, good penetration resistance, superior chemical resistance, temperature resistance and moisture resistance. It is suitable for the packaging of frozen food and food, medicine, industrial products and cosmetics. 4. Aluminized film. The main characteristics are high strength, good temperature and chemical resistance, good processing and anti-aging properties, and proper corona treatment, which makes the adhesion of the aluminum layer and the film stronger. After being used for aluminum plating, it can be widely used in food packaging bags such as tea, milk powder, candies, biscuits, etc., and can also be used as decorative film such as flower crafts, Christmas trees and other decorations; at the same time, it is also suitable for printing composite bags or cardboard composite bags And other packaging films.

Water-soluble film packaging has gained popularity in various industries due to its numerous benefits, especially when it comes to seed bags. This innovative packaging solution offers a range of advantages, including environmental friendliness, convenience, and product protection. In this article, we will delve into the benefits of water-soluble film packaging for seed bags, exploring how it can revolutionize the way seeds are stored, transported, and used.

Environmentally Friendly

Water-soluble film packaging is an environmentally friendly solution that can help reduce waste and lessen the impact on the environment. Traditional packaging materials, such as plastic bags, can take hundreds of years to decompose, contributing to the growing problem of plastic pollution. In contrast, water-soluble film is biodegradable and breaks down quickly in water, leaving behind no harmful residues.

By using water-soluble film packaging for seed bags, companies can demonstrate their commitment to sustainability and reduce their carbon footprint. Consumers are increasingly seeking out eco-friendly products, and choosing water-soluble film packaging can help businesses appeal to this environmentally conscious market segment.

Moreover, water-soluble film is often made from renewable resources, further enhancing its eco-friendly credentials. By opting for this type of packaging for seed bags, companies can contribute to a more sustainable future for the planet.

Convenient and Easy to Use

Another key benefit of water-soluble film packaging for seed bags is its convenience and ease of use. The film dissolves quickly in water, making it effortless for consumers to plant their seeds without having to remove the packaging manually. This convenience is particularly advantageous for large-scale agricultural operations, where time and efficiency are of the essence.

Furthermore, water-soluble film packaging eliminates the need for excess packaging materials, such as plastic or paper, streamlining the packaging process and reducing waste. This can lead to cost savings for businesses while also benefiting the environment.

In addition, water-soluble film packaging is versatile and can be customized to fit different sizes and shapes of seed bags. This flexibility allows companies to tailor their packaging to meet the specific requirements of their products, enhancing the overall user experience for consumers.

Product Protection

One of the most critical benefits of water-soluble film packaging for seed bags is its ability to protect the seeds during storage and transportation. The film acts as a barrier against moisture, oxygen, and contaminants, helping to maintain the quality and viability of the seeds for longer periods.

Seeds are susceptible to damage from external factors such as humidity, temperature fluctuations, and exposure to sunlight. Water-soluble film packaging provides a protective layer that shields the seeds from these elements, ensuring that they remain in optimal condition until they are ready to be planted.

Moreover, water-soluble film packaging can help prevent cross-contamination between different seed varieties, protecting the genetic purity of the seeds. This is particularly important for companies that produce and sell a wide range of seed types, as it can help maintain the integrity of their seed stock.

In conclusion, water-soluble film packaging offers a range of benefits for seed bags, including environmental friendliness, convenience, and product protection. By choosing this innovative packaging solution, companies can demonstrate their commitment to sustainability, streamline their packaging process, and ensure the quality of their seeds. Investing in water-soluble film packaging can not only benefit businesses but also contribute to a greener and more sustainable future for the planet.
