Package
Export packing | |
1 | polybag packing is the most commonly used packaging and standard export packing |
2 | mainly in order to protect the products, in the process of transportation can prevent the surface damage of products |
3 | for small size (od 8mm-19mm ) usually 5-10 pcs / bag, others size is 1 pcs/bag |
4 | advantage of polybag packing: a variety of colors polybag for your choice (red, blue, black, pink, white, transparent and so on, as your require) you also can print your company name, brand name, logo on polybag, to make your products more beautiful and more features |
