In the standardized production of industrial packaging, the unstretched flat bag machine has become the core equipment of high-end industrial flat bag production with its advantages of tension-free forming, flat bag body, precise size and undamaged fabric. Unlike traditional bag-making machine, traditional bag-making machine can only produce high-precision, common universal weaving bag. non-tensile equipment focuses on high quality, high regularity and high performance bag processing. It is especially suitable for all kinds of industrial flat bag products, with strict requirements of smoothness, sealing, bearing capacity, appearance accuracy, etc. Many manufacturers only know that the finished product quality of the equipment is good, but the appropriate type of flat bag is not very clear. This article introduces the mainstream production category of unstretched bag making machine in detail to help enterprises match equipment and production demand accurately.
First of all, BOPP laminated feed industry flat bag is the core production category of this equipment. Covering livestock and poultry feed, aquatic feed, pet food and other whole breed feed packaging, is the feed industry standardized mass production of the main products. The flat bag coated with feed film is covered with a dense protective film. Traditional tensile equipment is prone to wrinkling, layering and deformation, which affects the moisture and freshness of the film. And in the case of non-stretching, the whole process will be formed flat, can maintain the sealing and leveling. Feed bag size standard, cloth bag surface flat, firm edge sealing, suitable for 20-50 pounds of large packaging, meet the requirements of wet-proof feed storage, wear-resistant long-distance transport, orderly stacking in batches and other industrial applications.
High-end color printing custom industrial flat bag is an iconic product of stretch bagless machine. The packaging of branded agricultural inputs, oils, grains, fodder and chemicals typically requires customized flat packaging with high-definition color printing, symmetrical patterns and flat layouts. When drawing wire and feeding material, ordinary bag maker will cause stretch and distortion of printed patterns, line deformation, color misalignment, etc., which doesnot conform to brand packaging standard. Non-tensile flat bag machine relies on a a uniform and tension-free forming process to ensure that the fabric is smooth and stretched throughout the process. Printing pattern complete, no distortion, color unity, clear. Box angular, regular, fully adapted to brand customization, boutique export, high-end supermarket circulation and other industrial packaging needs. It is essential equipment for brand packaging production.
High precision grain and oil storage and transportation flat bag is also an important production variety of this equipment. Grain, millet, bran, miscellaneous grains and other agricultural by-products storage cycle long, the packaging bags of smoothness, sealing and structural stability requirements are extremely high. The grain bags weaving structure produced by traditional stretching technology has uneven tensile deformation, easy to appear moisture permeability, dust permeability, material leakage, etc., which is not conducive to long-term grain storage. The grain flat bag produced by non-tensile process has complete weaving texture, compact and even surface and uniform dimensions. Effective dust and moisture protection, multilayer stacking, not deformation. Suitable for grain depots storage in bulk, grain transit transport, processing and packaging of agricultural by-products, etc..
Special industrial flat bags for chemical powders and granular materials are also produced using non-tensile equipment. Chemical raw materials, building powder, industrial particles and other dust content is high, easy to leakage, which puts forward strict requirements for the sealing accuracy and bag body flatness. It is easy to cause uneven width and edge deviation in the process of stretching bag, and easy to leak powder and edge breakage after bagging. The non-tensile bag making machine has high forming accuracy, uniform edge sealing and no deformation or gap deviation, which can effectively prevent fine material leakage and pollution. At the same time, the bag has uniform bearing capacity, can be adapted to heavy industrial material packaging, meet the safety packaging standards of the chemical industry.
Weatherproof and anti-aging outdoor industrial flat bags are an important category suitable for special working conditions. Modified anti-aging woven materials are mainly used in industrial packaging bags, requiring open stacking, long-distance shipping and outdoor recycling. The main features of this flat bag are corrosion resistance, UV resistance, high and low temperature resistance. Once stretched, the structure of the material will be damaged and weather resistance will be greatly reduced. The non-tensile process does not damage the molecular structure of the fabric, and the material's outdoor protective properties can be fully maintained. The flat bag is suitable for long-term storage and transportation of engineering materials, outdoor agricultural inputs and exported industrial raw materials.
In addition, lightweight industrial flat bags are also suitable for production of the equipment. Including small auxiliary material packaging bags, food additive packaging bags, lightweight material storage flat bags, and so on, these products are lightweight fabric, easy to deformation, common equipment production defect rate is extremely high. The forming problem of thin-walled fabric is solved perfectly by the tensionless bagging process. The finished product is smooth and neat, the dimensions are accurate, and there are no loose and curly problems. Suitable for standardized production of small and medium-sized industrial packaging.
Overall, the non-stretchable bag maker mainly produces a variety of high-precision, high-performance, high-appearance industrial bag, including laminated feed bags, color printed custom bags, grain and oil storage bags, chemical powder bags, weatherproof outdoor bags, lightweight fine bags and other mainstream products. We specialize in high quality molding and low loss production to accurately match the standardization, branding and durability needs of modern industrial packaging. We are currently the core equipment of high-end woven flat bag production line.
