Non-woven packaging bags are made of non-woven fabric and are a kind of eco-friendly bag. They are moisture-proof, breathable, flexible, lightweight, non-flammable, easy to decompose, rich in color, low cost, and recyclable. Some customers have said that when ordering non-oven bags, they smell very bad, even a bit sharp to the nose. It is mainly related to the following two factors.
1. Problems with the fabric itself
Non-woven fabrics are divided into new materials and recycled materials. If the non-woven fabric is a new material, the fabric will not have any smell, but if it is a recycled material that contains other impurities, the fabric will inevitably have some smell.
2. Differences in printing methods
Non-woven bags may have odors due to problems with the selection of inks used for printing. The more environmentally friendly the ink, the less odor. Generally speaking, oil brushes are very environmentally friendly and have less odor. Is offset printing relatively smelly? The smell is a bit strong, but the smell will gradually go away with time.
Above is the editor's explanation of the cause of odor in non-oven bags. I will explain to you two main reasons for non-oven bag odor. I hope it will be helpful for you.
