How Does DGKAYRUN Make High-Quality Paper Straws?

2025-08-26

As global environmental awareness rises, paper straws have become the mainstream alternative to plastic straws, spurring strong demand in catering, hospitality, and retail. For businesses seeking reliable solutions, understanding the production process, quality control system, and core components of paper straws is essential. Today, we'll take a deep dive into the professional production system of DGKAYRUN (official site: https://www.dgkayrun.com/), a leading manufacturer of paper straw equipment and products, to uncover the secrets of high-quality paper straws.

Two Core Production Processes for Paper Straws: Adhesive-Free vs. Adhesive-Based

DGKAYRUN's production lines cover two mainstream technologies for paper straws, balancing diverse market needs with food safety and durability.

Adhesive-Free Paper Straws: Heat-Sealing for Eco-Friendliness

This process uses advanced heat-sealing tech (no extra binders) to bond paper layers, ideal for brands pursuing "zero chemical additives" in paper straws:

Step 1: Raw Material Prep: Choose patterned paper or print custom designs on white paper with food-grade inks, meeting brand personalization needs.
Step 2: Slitting: Cut wide paper rolls into narrow strips of specified width, matching the final paper straw's diameter and length.
Step 3: Paper Roll Fixing: Mount slit rolls on dedicated holders for stable, smooth feeding in subsequent processes.
Step 4: Heat-Sealing Bonding: Feed strips into a heating system; heat-sealing strengthens layer adhesion—no glue used, ensuring compliance with food contact safety standards.
Step 5: Rolling & Forming: Multiple paper layers are wound into long tubes via a roller belt system, shaping the base of paper straws.
Step 6: Cutting & Packaging: Cut long tubes to customer-specified lengths, then package (bulk or individual) for final delivery.

Adhesive-Based Paper Straws: Water-Based Glue for Better Durability

For paper straws needing higher water resistance (e.g., iced drinks), DGKAYRUN uses food-grade water-based adhesives to boost durability:

First three steps (raw material prep, slitting, roll fixing) match the adhesive-free process.
Step 4: Gluing: Feed strips into a tank with food-grade water-based adhesive, ensuring even coating and no toxic residues.
Step 5: Rolling & Forming: Same as adhesive-free—paper is wound into long tubes via roller belts.
Step 6: Drying: Send formed tubes to a drying room to remove excess moisture (critical to prevent softening or deformation of paper straws).
Step 7: Quality Check & Packaging: Inspect each batch's adhesion and shape; package as required after passing tests.

Quality Control: The Backbone of Reliable Paper Straws

DGKAYRUN enforces strict quality management throughout paper straw production, ensuring compliance with global food safety standards (FDA):

Pre-Production Prep

Equipment Cleaning: Remove rust inhibitors, stored dust, and residual impurities from production equipment to avoid contaminating paper straws.
Equipment Lubrication: Only after cleaning, use filtered, standard-compliant lubricant—fill to specified levels for smooth operation without product contamination.
Component Inspection: Fully check internal parts (e.g., cutting blades, rotating shafts); replace damaged parts immediately to avoid defective paper straws.

In-Production Supervision

Raw Material Screening: Select food-grade paper, inks, and adhesives; reject unqualified materials to ensure paper strawsafety from the source.
Workshop Hygiene: Keep workshops well-ventilated and clean; employees wear sanitized uniforms to prevent cross-contamination of paper straws.
Equipment Operation:
- Adjust inner blades continuously during cutting to keep paper straw lengths uniform.
- Reduce equipment speed appropriately to minimize wear and mechanical failures, ensuring stable paper straw
- Stop equipment immediately if malfunctions occur; cut power before maintenance to avoid accidents and protect the production line.
Batch Testing: Conduct sampling tests (water resistance, adhesion strength) on each batch of paper straws to ensure compliance.

Post-Production Storage

After packaging as required, store paper straws in open, ventilated, dry areas away from heat sources—prevent moisture absorption and softening, preserving usability.

Q&A: What Defines High-Quality Paper Straws?

What Determines a Paper Straw's Inner Diameter?

During paper straw forming, a rotating shaft is used to wind multiple paper layers. The shaft's outer diameter directly determines the final paper straw's inner diameter. DGKAYRUN offers customized shafts to meet needs for different scenarios (e.g., smoothies, cold drinks).

What's the Role of Belts in Paper Straw Rolling Machines?

Initial rolling belts are key to paper straw production—they ensure accurate initial winding and positioning of paper, stabilize the production line, and boost efficiency and precision. DGKAYRUN's specialized belts for paper straw equipment have these features:

Material: Nylon + wear-resistant rubber (balances flexibility and durability).
Thickness: 1.0mm–6.0mm (customizable for different paper strawthicknesses).
Temperature Resistance: -20℃ to 80℃ (adapts to various workshop environments).
Key Advantages: Anti-slip, wear-resistant, high tensile strength, non-deformable—ensuring long-term stable operation of the paper straw production line.
