Now the packaging materials of moon cakes on the market are mainly paper, plastic and iron box. Among them, plastic accounts for as much as 60%, followed by paper, accounting for 25%. In terms of the above three types of materials, which is a good packaging material? Does using more mean that it is a good moon cake packing box material? The answer is No. although plastics have high variability, strong flexibility, light weight, easy transportation, good printability and recyclability, they are all the reasons why plastic containers are more selected. However, the disadvantages of plastics are heat resistance, insufficient light barrier and poor solvent resistance (especially grease). Therefore, the bottleneck of plastic containers is that they can’t steam at high temperature, wash with water and shine. In addition, considering the stability of the contents, some moon cakes are not suitable for loading in plastic containers. Compared with plastics, iron box manufacturers have better iron box packaging. Tinplate box has obvious advantages over other packaging materials.
1. Good mechanical properties: compared with other packaging containers, such as plastic and paper containers, the iron box has high strength, good rigidity and is not easy to crack. It can not only be used for small sales packaging, but also the main container of large transportation packaging.
2. Excellent barrier: the iron box has better barrier, gas barrier, moisture resistance, light shielding and fragrance retention than any other material. In addition, it has reliable sealing and can reliably protect the product.
3. The interior of the moon cake iron box will be coated with a layer of harmless coatings such as epoxy resin and phenolic resin, which will not pollute the moon cake and is harmless to human body, and has good corrosion resistance. It can prevent the deterioration of oil and medium in the moon cake, so as to effectively protect the quality of the moon cake.
4. Exquisite decoration: good performance of metal materials; The pattern and trademark are bright and beautiful, and the prepared packaging container is attractive. It is an excellent sales packaging.
5. The moon cake iron box can be recycled, environmentally friendly and safe, which is the trend of moon cake packaging in the future.
Because of its advantages, tinplate as moon cake packaging is now more and more accepted by tinplate manufacturers. Breaking the traditional thinking mode of moon cake packaging and boldly adopting tinplate as moon cake packaging has become the development trend of the industry.
