Moisture-proof packaging technology and new material moistureproof packaging technology and new material
in recent years, with the improvement of people's living standard, the demand for goods packaging is higher and higher. Corrugated carton packaging containers as commodity, should not only can ensure the safety of the transportation of goods, and beautify the goods, improve the added value, promote the sales. Especially in recent years on the market of a new type of moistureproof beautifully printed glazed carton, to a large extent improved the product quality of packaging cartons, and fundamentally solve the carton packing easy to tide, easy to mildew, delicate problem. Corrugated carton be affected with damp be affected with damp or after oil penetrate through, strength will decrease rapidly. Appearance, softness will change because of be affected with damp be affected with damp. Because the carton box compressive strength after water infiltration, burst degrees will be greatly reduced, this will seriously affect the quality of the packaging. For example: under 95% relative humidity environment, corrugated carton can be lost two-thirds rhyme original strength, corrugated carton will have collapsed as a whole. Cartons with waterproof performance of the market demand is growing, especially in vegetables, food, household appliances, industrial products packaging application is gradually increased. Especially the export products to the rapid growth of the dosage of the water resistance of the cartons greatly promote the development of corrugated box manufacturing.
waterproof board is a resistance to water damage the strength of the floorboard of the cardboard. Moistureproof making corrugated carton, in addition to protect packaging from water soaked, main is to prevent water infiltration of the body itself.
moisture-proof, waterproof corrugated board development concern. Because of the corrugated carton absorption of moisture or water will cause the loss of stacking strength greatly, has become a carton production enterprise important problem presses for solution. The most common way is on the base paper coating agent. The first is the use of tung oil) on the carton, in order to achieve the waterproof, moisture-proof function. Chitosan by impregnation and acetic anhydride acetic acid solution, into chitin, coating on the base paper also has good moisture-proof, waterproof function. Using paraffin wax, microcrystalline wax, polyethylene wax, beeswax, pewter, carnauba wax, montan wax and other animal and plant wax, after emulsion coating on the board can also be moistureproof and waterproof, because the cost is low, is currently the most used method. But this approach surface characterization of resistance is poor, low gloss, can join allyl polymer, phenolic resin, epoxy resin, amino resin, amido, gathering carbamate and guildline of thermosetting polymers, such as PVC made from composite structure of drawing water, to impregnated paper, paper board waterproof, moistureproof performance can be greatly improved. Waxed corrugated board is not conducive to recycling, the eu has begun to restrict the use of. Another kind of drawing is the chromium trioxide in propyl alcohol - water Reduction in hydrochloric acid solution, and the stearic acid made from, both mouldproof, antifouling characteristics. Currently on the market have different formula of drawing water for sale. If the resin, the type of starch or glues moistureproof agent to join in the pulp copy moistureproof paper, nature of carton production is the most convenient, although this will increase the cost of some base paper, but the total cost and economical. 5 mm thick pure iron foil, the antirust processing, zinc plating, nickel or tin with kraft paper, polyethylene film extrusion composite composite board, used to make the cartons, not only waterproof, moistureproof, still can shield the electromagnetic wave, antistatic, especially suitable for aquatic products, fruit and vegetable, electronic instrument, semiconductor devices and mechanical and electronic products packaging. The aluminized PVC composite film and kraft paper carton, also has the waterproof, moisture-proof function. Conversion table packaging printing knowledge
