哥斯达黎加采购需求：小袋和收纳袋，小袋和收纳袋，拉链自立袋

I'm looking for a supplier to manufacture sachets for protein powders in two sizes: one for around 35 grams and another for about 6 grams. The packaging needs to be suitable for fine powders, ensuring strong seals and protection for quality maintenance. Could you provide info on available materials, customization options like printing and finishes, minimum order quantities, lead times, and estimated pricing? Also, do you offer filling services, or is it strictly packaging production? Thanks!
