In recent years, paper straws have become one of the most visible alternatives to single-use plastic. Banned in many countries and replaced in millions of food and beverage businesses, plastic straws are steadily giving way to their eco-friendlier counterpart: the paper straw. But how are paper straws made? What goes into producing a biodegradable, food-safe drinking straw that can withstand moisture and still protect the environment?
In this article, we explore exactly how paper straws are produced, from raw materials and manufacturing steps to new innovations in adhesive-free technology.

What Are Paper Straws and Why They Matter
Paper straws are disposable drinking tools made from multiple layers of biodegradable, food-safe paper. Designed to replace plastic, they break down naturally in composting environments and are often certified for food contact safety. Their increasing popularity stems from growing environmental awareness and regulations aimed at reducing plastic pollution.
A high-quality paper straw should meet the following criteria:
- Made from FSC-certified or recycled paper
- Safe for contact with food and drinks
- Moisture-resistant for 2–4 hours of use
- Compostable and free from harmful chemicals like PFAS
There are various types of paper straws: straight, flexible, wide (for bubble tea), and even branded custom options for cafés and restaurants.
Key Raw Materials & Safety Certifications
The first step in understanding how paper straws are made is to look at the core materials involved.
Paper
Most manufacturers use food-grade kraft paper or white paper rolls. These are often FSC-certified and meet FDA or BfR standards for food contact. The paper needs to be strong, absorbent-resistant, and safe to biodegrade in less than 60 days.
Adhesive
To bond the paper layers, producers use either water-based adhesives or hot-melt glues. These glues are non-toxic, fast-drying, and often FDA-approved. They play a crucial role in ensuring the straw remains intact when submerged in liquids.
Coating (optional)
Some straws include a thin coating to improve water resistance. Common options include:
- Acrylic coating
- Wax or paraffin
- New innovations that avoid chemical coatings altogether
However, not all coatings are compostable, and some may contain PFAS a group of "forever chemicals" now under strict scrutiny. The trend is shifting toward coating-free or natural fiber protection methods.
How to Make a Paper Straw at Home
While industrial machines produce millions of paper straws daily, the concept is simple enough to replicate at home for educational or creative purposes.
Here’s a basic DIY method:
- Cut strips of food-safe paper (1–2.5 cm wide)
- Use a thin stick or skewer (mandrel) to wrap the paper around
- Apply a small amount of glue as you roll
- Slide off the stick and trim the ends
- Let the straw dry for several hours
- Optionally, coat with wax or beeswax for water resistance
This simple process helps students and eco-conscious individuals understand how paper straws are produced and encourages sustainable thinking.
How Paper Straws Are Produced at Industrial Scale
At the commercial level, paper straw production involves advanced machines and strict quality controls.
Here’s how the process typically works:
- Paper rolls are fed into a slitting machine to create long, narrow strips
- The strips are passed into a core-winding machine that wraps 3 layers (ply) of paper around a steel mandrel
- Food-safe glue is applied between each layer during winding
- The straw is cut to length, then moved through a dryer
- Finished straws are sorted, tested, and packaged
This process allows manufacturers to produce thousands of straws per hour with consistent shape, strength, and hygiene.
Innovation in How Paper Straws Are Produced
Recent advancements in sustainable packaging have transformed how paper straws are produced. One of the most notable changes is the elimination of glue and chemical coatings.
Rigid Fiber, for example, has developed a process where paper straws are made without any adhesive or coating only compressed, specially-treated paper. These straws remain durable in hot and cold liquids for hours and are 100% compostable.
Other innovations include:
- Laser scoring to replace ink-based branding
- Smart paper layering for better strength without coating
- Eco-friendly drying methods to reduce energy consumption
Quality Testing and Product Standards
Producing paper straws at scale isn't just about volume it also demands consistency, safety, and performance. That's why rigorous quality testing is an essential part of how paper straws are produced.
Soak Resistance
Paper straws are typically tested for how long they remain usable in liquid. A standard target is 2–4 hours in cold drinks before softening. High-end paper and adhesive combinations can sometimes extend this to 6 hours or more.
Taste and Odor Control
Poor-quality straws may impart a cardboard-like taste or unpleasant smell. Top manufacturers use chlorine-free, food-safe paper and glues that ensure a neutral drinking experience.
Certifications
To ensure product reliability and market access, paper straw manufacturers often pursue:
- FDA food contact compliance
- BfR standards (Europe)
- ISO 22000 (food safety management)
- SGS certification (third-party lab testing)
- Compostability or home-compost certification (e.g., TUV Austria)
Straws free from PFAS (per- and polyfluoroalkyl substances) are especially preferred in markets like the U.S., Canada, and EU countries where such chemicals face bans or restrictions.
Environmental Impact of Paper Straw Production
Paper straws are often promoted as “eco-friendly,” but it’s important to consider their entire life cycle from raw material sourcing to disposal.
Breakdown and Composting
Unlike plastic, paper straws can degrade in 30–60 days under composting conditions. Many are suitable for industrial composting, and some can be composted at home, depending on the glue and coating used.
Resource Use
Even though paper is biodegradable, the production process still consumes:
- Water (for paper pulp)
- Energy (drying, cutting)
- Chemicals (if coating or dye is applied)
Thus, manufacturers are working to optimize energy and water efficiency and use recycled paper where possible.
Hidden Environmental Concerns
Some paper straws may contain:
- Synthetic glues with microplastic content
- Coatings that prevent biodegradation
- Ink dyes that leach into drinks or soil
To truly minimize environmental impact, the best options are glue-free, coating-free, and ink-free paper straws, produced using non-toxic, natural materials.
Paper Straw Production for Businesses
If you're a business whether in F&B, retail, or sustainable packaging understanding how paper straws are produced helps you make smarter purchasing decisions.
What to Look for in a Supplier
- Food-grade paper and glue certifications
- Custom branding with safe, compostable inks or laser marking
- Soak-time rating (verified by lab)
- Batch testing reports and sample options
Logistics Considerations
- Minimum Order Quantities (MOQ) may start from 10,000 units
- Options for private label production
- Regular delivery cycles for restaurants, cafés, and hotel chains
Choosing the right supplier also gives your brand credibility in eco-conscious markets, helping you meet both customer demand and sustainability goals.
