Water soluble bag manufacturers are a rapidly growing industry. The reason for this is that this type of packaging has the potential to revolutionise how we use and dispose of our products. These bags are hygienic, environmentally friendly and provide a great alternative to traditional plastic bags. They are also available in a range of sizes. Some are designed to be used in maternity wards and other areas where garments are likely to be exposed to higher moisture levels.
The key difference between this kind of packaging and the traditional LDPE polybags is that they are completely biodegradable and water soluble. Once dissolved, the bag turns into carbon dioxide, water and biomass. This decomposition takes place by microbial and biochemical processes. This means that it is totally safe for marine life and will not enter the food chain. In addition, the water-soluble bags are odourless and will not leave any traces in the laundry or in the surrounding environment.
Moreover, these bags are available in a wide variety of colours including clear, red and green. They are also customised to suit client requirements. This makes them a perfect solution for a variety of applications and industries, including hotels, hospitals, nursing homes and schools. In addition, they can be used to package a variety of items such as soft homewares and clothing items.
Another advantage of these bags is that they are highly recyclable and meet the minimum standards set by environmental agencies. In fact, they can be recycled along with other cellulose-based materials. This is in contrast to polyethylene (PE) and polypropylene non-woven bags, which are unable to be recycled.
This is because these bags are made from polyvinyl alcohol, which has been derived from corn starch or wheat glucose. This is a renewable resource, and it has been found to have better tensile strength than polyethylene. In addition, it is heat and cold resistant and can be printed on.
Some PVA bags are even labeled as marine degradable, but this is a claim that needs further investigation. In a recent white paper on their website, one of the leading producers of hot-water soluble PVA film for polybags states that the material is not fully marine degradable.
This is because the material only breaks down under specific conditions. Therefore, it would only be possible to classify it as marine-degradable at a thickness of 15 mm or 20 mm, which is much thinner than the typical grade for hot water soluble PVA bags. In addition, the product is only considered industrially compostable under certain conditions and not for use in home compost heaps. The industry is now working on solutions to address these concerns. One of these is the introduction of new technologies to make PVA bags more marine-degradable and more suitable for home composting. This will help to address the problem of microplastics and other pollutants in the marine environment. However, it will take some time to develop this technology.
