Rice bags size and material which is really good
rice bags according to the material can be divided into two kinds: custom bags, woven bags. According to the bag type is divided into three types: portable bag, brick 3-side, rice bags. By the gram weight is divided into: 500 g, 1 kg, 2 kg, 2. 5 kg, 3 kg, 5 kg, 10 kg, and many other specifications. Packing is the preferred choice, protection, security, good, good processability, reasonable cost, packaging standards and regulations under the condition of ensure the quality of rice. Custom bags for rice is a kind of excellent packing sealing, compounded by the PA/PE, moistureproof oxygen insulation performance is good, which can effectively prevent mildew and insect.
rice usually choose woven bags, craft is the OPP film, pearl film, matt membrane after printing, and compound bag and transparent woven cloth and bags. Our company production of rice bag specifications are: 5 kg, 10 kg, 15 kg, 20 kg, 25 kg, 50 kg, etc. ; Size, layout, color, weight, thickness can be customized according to demand. Aluminum foil bags, plastic bags
size is as follows: 5 kg: 30 cm wide & times; 45 cm long, 10 kg: 35 cm wide & times; 55 cm long, 15 kg: 40 cm wide & times; 62 cm long and 20 kg: 45 cm wide & times; 70 cm long, 25 kg: 45 cm wide & times; 75 cm long, 50 kg: 55 cm wide & times; 95 cm long
rice packaging form is determined by the material, commonly used plastic woven bag and composite materials are mainly two kinds of plastic bags, so the corresponding packing form is divided into ordinary packaging, custom packing and gas 3 kinds.
rice packaging, rice the ordinary ordinary packaging is using polypropylene material such as plastic woven bag of rice in packaging, sealed with stitches. Did not exert any technology in the process of packaging, packaging of insect-resistant, mouldproof, and preservation of the effect is relatively poor, normally only hold for food. Plastic woven bag, strong tensile strength of the packaging weight in rice more USES this kind of packing, shelf life in about three months.
woven bag is made from plastic film certain narrow band width, or use hot stretching method to get high strength, elongation of small plastic woven flat belt. Plastic woven bag is much taller than the strength of the plastic bag, and not easy to deformation, impact resistance, the surface is weaving lines at the same time, improve the skid resistance, easy to store when stacking. In more than 5 kg rice weight almost all packed in plastic woven bag material. Tea bags, composite bags
use plastic bag to packing of rice, packing method is simple, material moisture resistance is poor, poor barrier property, easy oxidation of rice, mildew, pest phenomenon is relatively serious, summer short shelf life. Suggest do not use this kind of packing way.
2, rice custom packaging
using custom packaging, can reduce the concentration of O2 in the packaging of storage, inhibit the respiration intensity of rice breeding, and mold prevent rice Chen, mildew and insect, better to keep the quality of rice. Choose the set of system of rice custom packaging is in commonly - 0. 07 ~ - 0. 09 between kPa. Due to large fixed system, wrapped tightly rice packaging materials, packaging bags are easy to broken rice, and the custom packaging. with the bag in the process of circulation, collision and the friction between fall is also easy to cause packaging bag. So on rice fresh-keeping packaging must be combined and circulation environment at the same time, in order to obtain good effect, the market accounted for most of this kind of packing way. Food packaging bags, custom bags
3, rice filling packing
inflatable generally is filling the CO2 and N2, they are colorless, odorless, non-toxic gas, relatively stable chemical properties. Rice has the ability of adsorption of CO2, form a protective layer, make the rice in the sleep state, and fatty acid, total acid, reducing sugar, viscosity change is relatively small, prolong the shelf life effectively; Filled with N2 O2 concentration reduces the storage environment, inhibit the growth of microorganisms in the rice, regarding the quality of the slow changes play an important role. Most research shows that the inflatable packaging can effectively keep the rice quality, prevent mildew and insect in rice.
custom packing and filling is made of rice, the composite plastic bags. Composite plastic bag is made of high barrier property of EVOH, PVDC packaging materials, PET, PA and PE, PP and other multi-layer plastic composite, this kind of packing than plastic woven bag packaging moistureproof, mouldproof, insect-resistant effect is better. Another design, trademark printing clearly, text, bar code is clearly visible, easy to attract customers, promote sales. Rice weight less than 5 kg in the vast majority of packed in compound plastic pouch. Bags, packing bags
using composite plastic pouch for packing rice, general with smoking custom or heat sealing after aeration technology. Due to the density of the material itself and custom, gas processing, basically solved the rice packaging mouldproof, insect-resistant, quality problems, have a certain promotion and practical value. But when compound bag packing in the sealing a thermal easy appear the wrinkling, affect the aesthetic of the packaging bags. In addition, the compressive strength of compound bag is not enough, some packaging, inflatable way in the transport process often appear broken bag phenomenon, thus affecting the shelf life of rice. Again, because the plastic bags is not easy to degrade, post-processing is more difficult, and plastic products have toxicity to make plastic bags used by certain constraints.
