The design principle and precautions of non-woven bag involves many aspects, the following is a detailed description of these two aspects: non-woven bag 1. non-woven bag design principle Material selection: non-woven bag raw materials are mainly polypropylene (PP) or polyethylene terephthalate (PET), these materials are environmentally friendly, non-toxic, degradable and other characteristics.
The chemical structure of polypropylene is not strong, and the molecular chain is easy to break, so it can be effectively degraded and enter the next environmental cycle in a non-toxic form.
Structural features: The non-woven fabric is not interwoven and braided by 1 1 yarns, but the fibers are directly bonded together by physical methods.
Non-woven bag with tough and durable, beautiful shape, good air permeability and other characteristics, suitable for a variety of packaging and carrying needs.
Production process: The production process of non-woven bags includes spunbond, meltblown, spunlace, thermal bonding and other methods.
These processes make non-woven bags have the characteristics of short process, fast production speed, high output and low cost in the production process.
2. non-woven bag design considerations size and capacity: according to the use of demand to determine the size and capacity of non-woven bags, to ensure that the bag can hold the required items and easy to carry.
Load-bearing capacity: Considering the load-bearing capacity of the non-woven bag, the design needs to ensure that the bag will not be damaged or deformed after being filled with items.
Durability: Choose suitable materials and process methods to improve the durability of non-woven bags so that they can withstand the wear and tear in daily use.
Environmental protection: Emphasize the environmental protection of non-woven bags to ensure that the materials are degradable and have little impact on the environment during the production process.
Aesthetics: Pay attention to aesthetics when designing, and enhance the visual effect of non-woven bags through color, pattern, shape and other elements to make them more attractive.
Printing and marking: The printing process needs to choose environmentally friendly and durable methods, such as screen printing.
Add the necessary logo and instructions on the bag, such as brand, size, load-bearing capacity, etc.
Storage and maintenance: inform the user of the correct storage and maintenance methods, such as avoiding damp, sun and rain and other environments, as well as regular cleaning and replacement of detergents.
In summary, the design principles and precautions of non-woven bags involve material selection, structural characteristics, production technology, size and capacity, load-bearing capacity, durability, environmental protection, aesthetics, printing and identification, storage and maintenance, etc. When designing non-woven bags, these factors need to be taken into account to ensure that the bag is both practical and beautiful, while meeting environmental requirements.
