Effective commemorative coins, rating coins packaging plastic welding machine to make products to achieve the advantages of moisture and oxidation, easy to preserve for a long time. Rating currency boxes such as single currency, Zodiac set, collection currency, paper currency and knife currency generally use PC, PVC, PETG or acrylic transparent material and use airtight seamless welding packaging process. One machine can change different moulds according to the specifications of the product can heat seal and weld a variety of product packaging.

Common rating currency packaging box plastic material is:
1: PS material, poor material blue light, rough feel, soft material, poor light transmission effect, cheap material, easy to achieve ultrasonic welding;
2: PMMA(acrylic), the product presents white light, smooth feel, hard material, good light transmission effect, the disadvantage is easy to break, easy to achieve ultrasonic welding;
3: PC polycarbonate, high transparency, smooth surface, super hard material, strong fall not broken, the material is more expensive, need higher power ultrasonic machine for welding.
Coins come in different sizes and shapes, and Jin guoheng tailor-made boxes of different specifications for each coin.

high quality box 6 standards :(aizang, cicc, huaxia, national product jinbao, NGC, quancheng, etc.)

Advantages of using ultrasonic welding to encapsulate rating coin boxes:
(1) The material of the coin box has high transparency and good stability, and zero damage to the coin
② Into the coin, high precision ultrasonic welding machine a thermal molding
Good tightness
④ Strong impact resistance
⑤ It is very stable under high temperature and extremely cold conditions

The falcon structure designed at the bottom of the box can stack many boxes firmly, greatly saving storage space.
