1、 Product parameters
1. Specifications and dimensions
There are multiple options for the specifications of non-woven bags according to their different uses. Non woven cloth bags commonly used for daily shopping, with sizes of 30cm x 40cm x 10cm (length x width x side width) and 35cm x 45cm x 12cm, can meet the needs of daily purchasing items; Small non-woven bags used for promotional activities, typically measuring 20cm x 25cm x 8cm or 25cm x 30cm x 8cm, are convenient to carry and suitable for storing small gifts, promotional materials, etc; Non woven bags used for storing larger items will have larger sizes, such as 40cm × 50cm × 15cm, 45cm × 55cm × 15cm. In addition, customized sizes such as curved bags, three-dimensional bags, etc. can be made according to customers' special needs.
2. Material selection
The material of non-woven bags is mainly non-woven fabric, and its weight is an important parameter. Common types include 60g, 70g, 80g, 90g, 100g, etc.
60g-70g non-woven fabric, with a relatively light and thin texture, is suitable for making bags for short-term promotion and carrying lightweight items, with low cost.
80g-90g non-woven fabric, with moderate thickness and toughness, has a wide range of applications and can be used in various scenarios such as daily shopping and promotional activities, with high cost-effectiveness.
Non woven fabric weighing 100g or more, with a thick texture, strong load-bearing capacity, and good durability, is suitable for making non-woven bags that require long-term use and carry heavy items, such as storage bags, shopping bags, etc.
At the same time, non-woven fabrics can be divided into pure non-woven fabrics and composite non-woven fabrics according to their material composition. Composite non-woven fabrics are made by laminating a thin film on the surface of non-woven fabrics, which can enhance the waterproof and durability of bags, and are suitable for storing items that may leak water.
3. Information Content
The information content on non-woven bags can be determined according to their purpose. Non woven bags used for commercial promotion, usually containing the brand name logo、 Promotional slogans (such as "Green Travel, Environmental Protection Accompanying", "XX Brand, Quality Choice", etc.), contact information (phone number, website, address, etc.); Non woven bags used for event commemoration will have information such as the event name, theme, time, and organizer; However, ordinary shopping non-woven bags may only have simple patterns printed or no excessive information. The information layout should be clear and eye-catching, highlighting the core content, so that the audience can quickly capture key information.
4. Accessories
• Handle: The material of the handle is mostly the same as the bag body (non-woven fabric), and cotton rope, nylon rope, etc. can also be used. The length of the handle depends on the size of the bag, generally ranging from 25cm to 40cm, to ensure comfort and convenience when carrying. The sewing methods of the handle include side stitching, top stitching, etc., to ensure firmness and prevent breakage.
Pocket: Some non-woven bags may be designed with an inner or outer bag. The inner bag can be used to hold small items, while the outer bag is convenient for storing common items. The pocket size is set according to actual needs.
Velcro/Button: Installing Velcro or buttons at the bag opening can seal the bag and prevent items from falling off, making it especially suitable for storing scattered items.
2、 Process Description
1. Printing process
Screen printing is a commonly used printing process for non-woven bags, suitable for printing simple patterns, single colors, or a small amount of colors. It has the characteristics of low cost and strong adhesion, which can clearly present patterns and text on the surface of non-woven fabric, and is resistant to friction and not easy to fade.
For non-woven bags with complex patterns and rich colors, heat transfer printing technology can be used. Heat transfer printing can achieve high-precision printing effects, with bright and full colors, realistic images, and can effectively reproduce complex design patterns. However, the cost is relatively high, making it suitable for products with high requirements for printing effects.
2. Cutting process
Using an automatic cutting machine to cut non-woven fabric, the bag body, handle, and other parts are accurately cut according to the set size. During the cutting process, it is necessary to ensure that the edges are neat and free of burrs, laying a good foundation for the subsequent sewing process. For non-woven bags with special shapes, corresponding cutting molds need to be made first before precise cutting.
3. Sewing process
Sewing the cut non-woven fabric components using an industrial sewing machine. The side and bottom seams of the bag are sewn with double threads to enhance its firmness and load-bearing capacity, avoiding cracking during use. The connection between the handle and the bag body is the key point of sewing, and it is usually reinforced and sewn multiple times to ensure that the handle is not easily detached. Sewing thread can be made of polyester thread in the same or contrasting color as the bag body, which is both firm and beautiful.
4. Post processing technology
Some non-woven bags will undergo edge pressing treatment, which uses high-temperature pressing to press the edges or sides of the bag mouth, making the edges smoother and enhancing the overall integrity and durability of the bag.
For non-woven bags that require waterproof function, a waterproof coating treatment will be applied on their surface. The coating material is environmentally friendly and non-toxic, which can effectively prevent water infiltration and improve the practicality of the bag.
Non woven bags can also be subjected to hot stamping and silver stamping processes, with hot stamping on brand logos, key text, and other areas to make these parts more eye-catching and enhance the bag's grade and texture.
The product parameters and process specifications of the non-woven bags mentioned above can be customized according to the specific needs of customers. We have professional production equipment and an experienced technical team to ensure product quality and provide customers with satisfactory
