U Shaped Straw Production Line

U Shaped Straw Production Line – Complete Solution for Automated Flexible Straw Packaging

U-shaped drinking straws are widely used in beverage boxes, milk cartons, and juice pouches for their convenience, hygiene, and easy storage. Unlike straight straws, U-shaped straws are pre-bent and individually packed in a “U” form, making them ideal for Tetra Pak-style packaging and ready-to-drink products.

What Is a U Shaped Straw?

A U-shaped straw is a flexible drinking straw that has been bent and packed into a compact “U” shape, often attached to the surface of beverage packaging. It provides a clean, compact, and user-friendly solution for single-use drinks, especially in school milk programs, vending beverages, and on-the-go markets.

Applications of U Shaped Straws

• Tetra Pak and carton beverage boxes

• Juice pouches and school milk packaging

• Convenience store single-serve drinks

• On-the-go drink brands and OEMs

• Hospital and healthcare packaging

How Are U Shaped Straws Made?

The U-shaped straw production involves three major processes:

1. Straw Extrusion

Raw plastic or PLA material is extruded into long, straight drinking straws using a Straw Extrusion Machine.

2. Straw Bending

Straight straws are automatically fed into a Straw Bending Machine, which bends them into flexible straws with corrugations.

3. U-Shaping and Packing

The flexible straws are shaped into a U form and individually packed by a U Shaped Straw Packing Machine. The packing format is typically four-side sealing using BOPP film, producing continuous strip or cut-pack options.
