博茨瓦纳采购需求：开口式装袋机、装袋设备、包装机械、工业装袋机、自动装袋机、手动装袋机

We are upgrading our flour mill in Ghana and need a solution for packing 50 kg woven polypropylene bags, with a capacity of 250 tons/day. The bag dimensions required are widths from 380 mm to 600 mm and lengths between 550 mm and 1050 mm. The free bag top should be at least 170 mm plus 60% of the bag thickness. We're looking for quotations for three options: a fully automatic machine that requires minimal operator input, a semi-automatic machine with manual bag placement, and a carousel-type system that enhances capacity while maintaining automation. Let me know if you need any further details to provide an accurate quote.
