How to choose the moon cake packaging, to help ~

Near the Mid-Autumn festival, a lot of baking private friends all start with all kinds of moon cakes, delicious handmade cakes and exquisite packaging, smoked in the Mid-Autumn festival gifts is necessary! But is like the moon cake will direct contact with the moon cakes, moon cakes packaging these products, how do we choose safer, health of moon cake packaging? Packing belt you know those things about the moon cake packaging! 让我们 年代开始! Moon cake's common material are: PVC, PP, BOPS three what is the difference between them? : PVC is a vinyl polymer material, its material is a kind of non-crystalline materials, optical, thermal stability is poorer. BOPS: is the abbreviation of two-way stretch polystyrene, belongs to the polymer new environmental protection material, hardness is strong, but more brittle. PP: polypropylene, is recognized as used to make the material of the safety of the food container, do not contain carcinogenic substance, 110 ℃ heat resistance; The characteristics of the with toughness, resistance to fall. Test a: weight is loaded with 75 grams of moon cakes, weight in comparison. PVC mooncakes weight is 1 g; BOPS mooncakes weight is 1. 4 g; PP mooncakes weight is 2. 3g。 （ After repeatedly weighed average data. ） Light transmittance test two: a single moon cakes is difficult to see that transparency, fold up when more mooncakes. We can see clearly that PVC material of moon cake permeability generally, the color is slightly yellow; BOPS material of moon cake permeability good, color is normal; PP material of moon cakes is not completely transparent, color slants milky white. Test three: material to distinguish how to identify? Can through simple combustion test - — We can see that the PVC material is flame retardant, BOPS material burns with black smoke, and no black smoke PP material burns. With handle gently pressing test four: the compressive degree, can be clear that PVC material cakes after compression is easy to deformation; The BOPS material cakes after compression deformation slightly; PP material of moon cakes after compression basic can also keep the prototype. Conclusion: after a round of testing, we can clearly see that moon cakes made of different materials have obvious differences. PVC material of moon cakes, lighter weight, transparency, defect is not compressive, mooncakes in transit may be prone to deformation, fracture and so on. BOPS material of moon cakes, medium weight, high transparency, environmental protection material, compressive ability is general, belong to the middle class products. PP material of moon cakes, the heavier weight, transparency, material resistant to high temperature, compressive ability is good, suitable for must express transportation of mooncakes. The moon cake how to save? Step 1: seal, completes the moon cake to into high cut off the moon cake packaging, heat sealing machine sealing seal save, can let the moon cakes from the air, form a closed environment. Step 2: deoxidizer, attention is deoxidizer, cannot replace oh with desiccant. Deoxidizer action principle is that when activated iron and air contact, via oxidation reaction, make molecular state oxygen ion state oxygen ions, so as to achieve the purpose of starvation. （ Left for the desiccant, right as deoxidizer) The effective composition of deoxidizing agent is active iron powder, make through oxidation reaction of oxygen concentration drops to zero in confined Spaces. Below 01%, and the purpose of the desiccant is to absorb the moisture in the environment, its effective ingredients for silica gel. Points is the model about deoxidizer models: deoxidizer oh, commonly used 20, 30 and 50, the higher the model, the higher the cost. Deoxidizer used principle is high not low, can't make mooncakes for a little bit of cost in the risk of mildew. （ Each brand model corresponding specification or have different) How to determine whether deoxidizer effective? 1. After open the fever. Open the packing, let deoxidizer and air contact after a fever is a way to determine whether effective, this method is simple and intuitive. However, not all can be used as deoxidizer. Some manufacturer use those who habits (considering you After unpacking to seal again there will be a long time) , so the oxidation reaction of deoxidizer post-processing, delay the deoxidizer, reaction time, in that case, would not immediately fever, that is if you buy this, how to judge? 2. Empty bottles of observation. In a empty water bottles, add a few grains of deoxidizer after sealing, 2 - To observe the effect after 4 hours. Because in the air of oxygen makes up about 20% or so, so after oxygen absorber reaction, the bottle will deeply to sink in, if only shallow shrink a little, also shows the effect of deoxidizer sent some, this method which can determine whether deoxidizer and use, also can be judged whether the deoxidization effect is obvious. Can choose the third step: cold storage, because now the temperature is higher, protein content is higher in moon cakes, easy metamorphism, refrigerate is a good choice, early return temperature when eating, or microwave oven, oven, bake, taste better! Well, said so much; Small make up, to tell you a good news! You don't have to so hard to go door to door contrast, looking for moon cakes; Because. 。 。 。 。 。 Sweet, we have help you ready!
