Oxygen scavenger (FreshPac), also known as oxygen scavenger, can be used in food, pharmaceutical or other products, products used to prevent decay, deterioration, moldy odor: With this kind of oxygen scavenger can keep the nutritional value of the product itself and avoid loss of quality. It can make the oxygen content of the package is less than 0.1%, and remained at that level. The series of notable features: △ prevents the growth of aerobic bacteria and its impact on the organization's destruction △ exclude some bacteria can grow rapidly △ conditions need to extend the shelf life of typical use: △ doses of medicine, vitamins △ food (bread , cakes, pastries, etc.) △ snack food product characteristics of the deoxy preservative within a short time inside the sealed bag in the air were reduced to less than 0.1% oxygen, making the packaging bag of food contaminated bacteria, fungi and other microorganisms and pests can not grow or die. The food grease and easily oxidized material without oxidation occurs due to oxygen, so as to achieve mold, pest control, anti-oxidation purposes. Use: deoxidizer in conjunction with high barrier packaging materials can be widely applied: Mid-Autumn moon cake, snowy moon cake, cakes, rolls, puffed food, biscuits, cookies, Nuomici, seafood, roasted, dry goods, etc. The deoxy food preservative to inhibit mildew, prevent fat rancidity, loss of aroma and vitamins and other nutrients oxidative deterioration, keep food original color, smell, taste and effects. In the ancient, heritage, precision instruments, tobacco and furs products and other applications, and the ability to achieve pest control, mold and prevent oxidation yellowing of the desired effect. Ingredients: iron powder, edible starch, activated carbon, salt usage: ⑴, when used, will be fresh food (items) together with the deoxy preservative compound bag placed in low oxygen permeability, sealing sealing, Note sealing strength and sealing quality, rendering leak; ⑵, this product has a 20 -, 30 -, 50 -, 100, etc. according to the amount of oxygen in order to accommodate different sizes of packaging volume; ⑶, non-toxic, tasteless, but do not eat. Requirements for food package bag: the oxygen permeability of less than 20ml / m 2? 24h? 25 ℃ composite materials to achieve the desired results. For example: package bag Type Thickness (u) oxygen permeability KOP / PE 22/40 20ml / m 2? 24h? 25 ℃ PET / PE 12/40 6 ~ 10ml / m 2? 24h? 25 ℃ PA / PE 15 / 40 15ml / m 2? 24h? 25 ℃ Note: If you use poor barrier properties (oxygen transmission rate) of packaging material or packaging seal is not tight, then the inevitable effect of reducing or even invalid. Requirements: After opening the package, preferably 1 to 2 hours spent and seal of fresh material, has not yet run out, immediately after the discharge of the original re-sealed bag in the air, in order to avoid failure.
