What is a composite bag?


A variety of materials with different characteristics are compounded to improve the air permeability, moisture permeability, oil resistance, water resistance, and chemical resistance of packaging materials, so that they can play an insect-proof, dust-proof, microbial-proof, light, fragrance, and odor Isolation, as well as heat resistance, cold resistance, and impact resistance, have better mechanical strength and processing applicability, and have good printing and decoration effects.

Classified according to the form of packaging: three-sided seal, yin and yang bag, middle seal, pillow bag, five-sided seal bag, eight-sided seal bag, self-standing bag, zipper bag, straw bag, coil, cover material, etc.

Classified by function: high-yin diaphragm bag, retort film bag, antistatic film bag, antibacterial film bag, anti-fog film bag, vacuum bag, anti-chemical film bag, deoxygenation film bag, modified atmosphere packaging film bag, etc.

According to the material classification: laser aluminum film paper material, laser transfer paper material, paper composite material, aluminum composite material, plastic composite material, fabric composite material, etc.

Finishing sensor: clean the detector cover regularly (once every four hours). When the machine is running, make sure that the white light is always on. The detector is designed according to the principle of infrared ray. Dazzling light will affect the performance of the sensor. Try to use only daylight tube near the machine. If the spindle surface is bright, the detector may not work accurately. Avoid using aluminum tube or black tube. Black yarn will make the detector unable to work.

Plastic packaging bags include plastic woven bags and plastic film bags. The former has the characteristics of light weight, high strength, corrosion resistance, etc., after adding plastic film lining, it can be moisture-proof; light bag load weight below 2.5kg, medium bag load weight 25-50kg, heavy bag load 50-100kg.


Definition of woven bag

The national standard GB/T8946-1998 stipulates that "the bag shall be flattened, and two squares of 100mm × 100mm shall be circled at the upper and lower diagonals of the bag. the outer edge of the square shall be 100mm apart from the edge line of the bag. the longitude and weft number of the squares shall be visually inspected and the average value shall be taken. when counting, when there is less than one ending point, it shall be counted as one." The national standard specifies the density of weaving and the density tolerance. The weaving density mainly depends on the packaging product and is determined by the user.


Application of packaging bag

Due to product resources and price problems, China has 6 billion woven bags for cement packaging every year, accounting for more than 85% of bulk cement packaging. With the development and application of flexible container bags, plastic woven container bags are widely used in marine, transportation and packaging of industrial and agricultural products. In the packaging of agricultural products, plastic woven bags have been widely used in aquatic products packaging, poultry feed packaging, covering materials for farms, sunshade for crop planting, windproof, hail shelter and other materials. Common products: feed woven bags, chemical woven bags, putty powder woven bags, urea woven bags, vegetable mesh bags and other fruit eye bags, mesh bags

Surfacing wear-resistant plates can be used in various loading and unloading equipment and sites, especially in bulk cargo loading and unloading systems such as iron ore and coal, grab bucket, hopper, bucket, coal drop pipe, discharge pipe, stacker-reclaimer and other components. These components often need to bear a large amount of impact, wear and friction. Surfacing wear-resistant composite steel plates are used in easy-to-wear parts, which is very important for prolonging the service life of these wear parts and reducing the downtime and maintenance of loading and unloading machinery.
