Durable-Corrugated-Box Germany Import and Export Companies

I am interested in moving cartons. I am especially looking for double-fluted (double-wave) cartons with a carrying capacity of 30-40 kg. My preference for dimensions is around 70x50x50 cm. Do you have products that meet these specifications? If so, can you share your product information and price offers? I would also like to learn about alternative sizes or product varieties.
