What Type of Paper Do You Use for Die Cutting?

Die cutting is one of the most widely used converting processes in packaging, printing, consumer electronics, medical products, labels, automotive components, and industrial manufacturing.

While die-cutting equipment and tooling are important, the choice of paper material often has an even greater impact on production quality, cutting performance, dimensional accuracy, and final product functionality.

Different paper grades offer unique characteristics such as stiffness, thickness, surface finish, tear resistance, and release performance. Selecting the wrong paper can lead to poor edge quality, tool wear, material waste, and assembly problems.

At Sanken, we help OEM manufacturers select and convert paper-based materials for precision die-cut applications across a wide range of industries.

So what type of paper should you use for die cutting?

Paper selection should always be based on the product's application, processing requirements, and performance expectations rather than simply choosing the lowest-cost option.

Why Material Selection Matters in Die Cutting

Every paper material behaves differently during cutting.

Factors that affect die-cutting performance include:

• Thickness
• Density
• Surface coating
• Fiber structure
• Moisture content
• Dimensional stability

The correct material helps achieve:

• Clean cut edges
• Accurate dimensions
• Efficient production
• Reduced waste
• Consistent quality

Improper paper selection can create significant manufacturing challenges.

Common Problems Caused by Poor Material Selection

Manufacturers may experience:

• Edge tearing
• Incomplete cuts
• Excessive dust
• Tool wear
• Registration issues
• Material deformation

Choosing the right paper helps prevent these issues before production begins.

Understanding Application Requirements

Before selecting a paper grade, engineers should consider:

The intended end-use should always drive material selection.

Kraft Paper

Kraft paper is one of the most commonly die-cut paper materials.

Known for its durability and strength, kraft paper is widely used in packaging applications.

Advantages

• High tear resistance
• Good dimensional stability
• Cost-effective
• Environmentally friendly

Applications

Common uses include:

• Protective packaging
• Shipping materials
• Industrial packaging
• Insulation products

Kraft paper performs particularly well in large-format die-cut applications.

Cardstock and Paperboard

Cardstock and paperboard materials provide greater rigidity than standard paper.

They are frequently used when structural support is required.

Advantages

• Excellent stiffness
• Superior printability
• Clean die-cut edges
• Good appearance

Applications

Common applications include:

• Retail packaging
• Product inserts
• Display materials
• Folding cartons

Paperboard remains one of the most popular materials for commercial die-cutting operations.

Coated Paper

Coated papers feature specialized surface treatments that improve appearance and printing performance.

Advantages

• Smooth surface finish
• Enhanced image quality
• Improved print resolution

Applications

Used for:

• Product labels
• Premium packaging
• Marketing materials
• Brand identification components

The coating may require specialized die-cutting parameters to prevent cracking or edge defects.

Release Liner Paper

Release liner papers play a critical role in adhesive product manufacturing.

These papers are coated with silicone or other release treatments.

Advantages

• Easy adhesive release
• Excellent dimensional stability
• Consistent processing

Applications

Common uses include:

• Adhesive tapes
• Labels
• Medical products
• Electronics assembly materials

Release liners are among the most frequently converted paper products in precision die cutting.

Common Release Liner Types

Material selection depends on adhesive characteristics and processing requirements.

Glassine Paper

Glassine is a smooth, dense paper commonly used in adhesive applications.

Advantages

• Smooth surface
• Excellent release properties
• Good dimensional stability

Applications

Used for:

• Labels
• Medical adhesives
• Electronics assembly products
• Protective films

Glassine is particularly suitable for precision die-cut components requiring accurate registration.

Medical Grade Papers

Medical applications often require specialized paper materials.

These papers are designed to meet strict regulatory and performance requirements.

Advantages

• Controlled porosity
• Clean processing
• Sterilization compatibility

Applications

Used in:

• Medical packaging
• Diagnostic products
• Healthcare devices

Medical-grade materials require strict quality control throughout the converting process.

Synthetic Paper

Although technically not traditional paper, synthetic papers are often processed using paper die-cutting equipment.

Common materials include:

• Polypropylene-based sheets
• Polyester-based sheets
• Specialty polymer papers

Advantages

• Water resistance
• Chemical resistance
• High durability

Applications

Used in:

• Industrial labels
• Outdoor products
• Durable identification systems

Synthetic papers often offer significantly longer service life than conventional paper grades.

Paper Selection for Electronics Manufacturing

Many electronic products utilize paper-based materials during manufacturing.

Examples include:

• Release liners
• Insulation papers
• Protective papers
• Carrier materials

These applications require:

• Consistent thickness
• Low contamination
• Dimensional stability

Precision die cutting ensures these materials meet strict assembly requirements.

Paper Thickness and Die Cutting Performance

Thickness directly influences cutting quality.

Thin Papers

Advantages:

• Easy cutting
• High-speed processing

Challenges:

• Curling
• Stretching

Thick Papers

Advantages:

• Greater rigidity
• Structural support

Challenges:

• Increased cutting force
• Greater tool wear

Material thickness should be considered during both design and process development.

How Die Design Influences Paper Selection

The complexity of the part geometry also affects material choice.

Simple shapes generally allow more material flexibility.

Complex designs may require:

• Higher strength papers
• Better dimensional stability
• Improved fiber structure

Fine features and narrow sections often demand premium paper grades.
