About Paper Straw Making Machine | Eco-Friendly Spiral Winding Straw Production Line

A paper straw making machine converts food-grade kraft paper into biodegradable drinking straws through slitting, gluing, spiral winding around a mandrel, multi-knife cutting and drying. Straws are usually built from 3–4 plies for strength and can be produced in various diameters and lengths. It helps brands replace plastic straws with a compostable, renewable alternative.

How to Choose

  • Straw diameter and length range: supported inner/outer diameter and cut length for your market
  • Paper plies and grade: 3–4 layers of food-grade kraft paper and print/coating requirements
  • Winding speed and cutting: servo multi-knife cutting system and line speed for stable output
  • Adhesive system: food-contact, water-based glue with consistent, safe seam bonding
  • Auxiliary and automation: air compressor, automatic paper-roll splicing, and drying configuration

Q: How many plies does a paper straw have?
A: Most machines build straws from 3 to 4 paper plies to balance strength, wall thickness and running speed.

Q: Are paper straws food-safe?
A: They use food-grade paper and food-contact, water-based adhesives; documentation and batch checks are recommended for traceability.

Q: Can diameter and length be changed?
A: Yes. By changing the mandrel and cutting settings you can produce different straw diameters and lengths for various drinks.
