Printed roll stock plays a central role in modern flexible packaging, especially where high-speed production, branding, and product protection are essential. Understanding what printed roll stock is and the key standards that define its quality and performance helps packaging operators, brand owners, and procurement teams make better decisions and ensure reliable packaging results.

What Printed Roll Stock Is

Printed roll stock refers to rolls of flexible packaging film that have been printed with graphics, branding, product information, or other visuals before being converted into finished packages. This roll form is typically used with automated form-fill-seal (FFS) or flow-wrap equipment, which forms bags or pouches from the printed film, fills the product, and seals it in one continuous process. Roll stock can be made from plastic films, laminated composites, foil, paper, or combinations of these materials depending on barrier properties and product needs.

Printed roll stock allows manufacturers to avoid pre-made bags or pouches, offering flexibility in package size and shape directly on the packaging line. This makes it ideal for a wide range of products including snacks, coffee, pet food, powdered goods, liquids, and industrial parts.

Key Standards for Printed Roll Stock

While specific formal industry standards may vary by region and product category, the following areas represent the practical criteria that professional packaging suppliers and manufacturers commonly apply when specifying printed roll stock:

1. Material Selection and Structure

The choice of film materials and laminated structures affects durability, barrier performance, sealability, and print quality. Common materials include:

• Polyethylene (PE) – flexible and heat-seal friendly

• Polyester (PET) – strong and printable

• BOPP (Biaxially Oriented Polypropylene) – good clarity and stiffness

• Foil and high-barrier laminates – excellent moisture and oxygen barrier

Each material must meet performance demands of the product, such as moisture resistance, puncture strength, and shelf life. Material combinations should be compatible with printing methods and sealing equipment.

2. Film Thickness and Strength

Film thickness (often measured in microns) directly influences the durability and handling characteristics of the roll stock. Thicker films resist tearing better at high machine speeds, while thinner films may reduce cost and material waste. Suppliers typically define thickness tolerances that suit specific packaging lines and product weights.

3. Printing Quality and Color Accuracy

Printed roll stock must meet defined standards for visual quality. This includes:

• Color consistency across the entire run

• Print registration accuracy so graphics align correctly with machine eye-marks

• Ink adhesion and durability so the print does not degrade during handling or filling

Flexographic and gravure are common printing processes for roll stock film, capable of delivering high-resolution graphics on plastic or laminated surfaces.

4. Core and Roll Dimensions

Roll stock is supplied on cores of defined diameter and width so it fits specific packaging machines. Typical specifications include:

Standards for these dimensions ensure smooth feeding, consistent tension, and minimal stoppages during production.

5. Eye-Marks and Registration Marks

Eye-marks are printed targets used by form-fill-seal machines to detect where to cut and seal. Standards for these marks include:

• High-contrast visibility

• Precise placement relative to graphics and cut patterns

• Compatibility with machine sensors

Proper eye-mark standards are essential for minimizing misfeeds, wrinkles, or print misalignment on finished packages.

6. Compatibility with Form-Fill-Seal Machinery

Printed roll stock must run reliably on the intended packaging lines, whether vertical (VFFS), horizontal (HFFS), or flow-wrap equipment. This includes matching guidelines for:

• Coefficient of friction to prevent slippage

• Sealing temperature range suitable for chosen films

• Tension and unwind control

Standards in these areas minimize film breaks, wrinkling, and downtime during production.

Benefits of Following Roll Stock Standards

Adhering to clear standards for printed roll stock delivers multiple operational and commercial benefits, including:

• High-speed production with fewer stoppages

• Consistent package quality throughout long runs

• Reduced material waste and inventory cost

• Better visual impact and brand consistency

• Improved product protection against moisture, oxygen, and handling stress

These benefits help packaging facilities deliver value in competitive markets.
