A: The coffee cup cover paper lid forming machine without glue, also known as cup lid forming machine, is an eco-friendly automatic equipment to produce disposable paper lids for coffee cups, paper bowls and beverage cups. It adopts ultrasonic welding or hot-press fusion technology instead of liquid glue to bond paper edges, producing plastic-free, glue-free paper cup lids for hot and cold drink packaging.
A: It uses ultrasonic fusion or hot air pressure to melt the PE/PLA coating on food-grade paper blank. The paper layers are fused together by heat and pressure, no glue added. The sealing joint is tight, leak-proof and food safe, fully complying with food contact requirements.
A: This cup lid forming machine works with food-grade single PE coated paper, double PE coated paper and PLA biodegradable coated paper. Recommended paper weight ranges from 260gsm to 350gsm, which is widely used for compostable coffee cup lids.
A: Standard molds support common coffee cup lid diameters such as 62mm, 70mm, 80mm, 90mm, 95mm, 110mm. We can customize molds for special cup or bowl sizes according to customers’ samples. One machine can switch different molds to produce various paper lids.
A: Normal running speed is 40–70 pcs per minute, stable operation with low defective rate. The actual output depends on paper quality, lid structure and machine parameter setting.
A: Yes. The automatic coffee cup cover paper lid forming machine finishes paper feeding, positioning, forming, sealing, punching and lid collecting automatically. Only one operator is needed for paper replenishment and inspection.
A: Yes. Finished glue-free paper lids can withstand hot coffee, tea and hot beverage within 85–90℃. The ultrasonic fused seam will not come apart under normal hot drink conditions.
A: Our cup lid forming machine can provide CE certificate. Finished glue-free paper lids meet food contact standards for European and American markets.
A: We provide 1-year warranty for core parts. Overseas technical support includes online video guidance for installation, commissioning, troubleshooting and spare parts supply. Overseas engineer on-site service is available upon request.
A: Standard machine lead time is about 30–45 working days after deposit receipt. Custom mold orders will take extra time according to mold design.
A: We can provide free finished glue-free paper lid samples for your material test. Machine trial run video is available. Customers are welcome to visit our factory to watch the coffee cup cover paper lid forming machine running on site.
A: Standard power supply: 380V, 3-phase, 50Hz, voltage can be customized for different countries. Stable air compressor with 0.6–0.8Mpa air pressure is required for normal operation.
