Due to the rise of chain coffee shops, milk tea shops and takeaway drinks, the "Double Wall Paper Cup Production Line" is one of the paper cup production lines with the highest added value and the fastest growing demand in the market. Double wall paper cups consist of two parts: Structure Material Function Inner Cup Single PE-coated paper (140–350gsm + 15–20gsm PE) Directly contacts the beverage, providing waterproof and leak-proof performance Outer Sleeve Uncoated paper (180–350gsm) Provides insulation, heat protection, and printing/display area Next, I'll explain how this production line is composed and the auxiliary relationships between each device. Overall line configuration A complete line configuration requires seven machines, including printing, die-cutting, waste stripping, inner cup forming, outer cup forming, paper cup inspection, and paper cup packaging. ( paper cup machine manufacturer is suitable for large-scale production.) Process Main Function ① Printing Prints brand designs on paper rolls ② Die Cutting Cuts printed paper rolls into cup fan shapes ③ Waste Stripping Separates individual cup fan pieces from die-cut sheets ④ Cup Forming Produces the inner cup (single wall cup) ⑤ Outer Sleeve Forming Wraps the printed outer paper around the inner cup ⑥ Cup Inspection Detects deformed or poorly bonded cups ⑦Cup Packaging Final step – packages finished paper cups 1.Print on unprinted rolls of paper 2.Place the printed roll paper on the die-cutting machine and die-cut it into flat sheets 3.Place the die-cut flat sheets into the Multi Functional FullyAutomatic Stripping Machine for stripping 4.After the above process is completed, you can put the Paper Cup fan on the paper cup machine to directly form paper cups. 5.The formed paper cups will be directly sent to the double-wallr paper cup machine through the transfer table to form double-wall paper cups Small-Scale Customization Solution(Flexible Production Configuration) For start-up factories or small and medium-sized customers, Mingyuan offers a more flexible configuration: You can directly purchase pre-printed paper cup segments for forming; Use a paper cup machine and a double-layer paper cup machine to form the inner and outer cups in one piece; For small batch customization of multiple designs, we can add a digital printing press (MY-500X) to print on demand and meet diverse orders. This solution offers low investment and quick results, making it an ideal choice for many small and medium-sized customers. Mingyuan Machinery can provide a variety of solutions for paper cup production lines.
