Overview

FprEN ISO 8367-1:2026 is an international standard developed by CEN, specifying the dimensional tolerances for general purpose paper sacks. It applies to paper sacks as defined in ISO 6590-1 and establishes uniform measurement and manufacturing tolerances, promoting consistency and quality in the packaging industry. This standard supports alignment across manufacturers, suppliers, and purchasers, ensuring compatibility in global supply chains for paper-based packaging solutions.

Key Topics

• Dimensional Tolerances: The standard provides specific tolerance values for the critical dimensional characteristics of paper sacks, such as length, width, bottom width, gusset width, and sack circumference.
• Grammage Tolerances: It outlines acceptable tolerances for the grammage (basis weight) of individual paper plies, coated papers, total sack plies, and polyethylene (PE) film liners, ensuring that material weights meet defined specifications.
• Measurement Methods: Reference is made to related standards, requiring methods and terminology from ISO 536, ISO 6590-1, and ISO 6591-1 for consistent sampling, measurement, and definitions throughout the manufacturing process.
• Compliant Sampling and Testing: The standard prescribes sample collection in accordance with ISO 7023 for uniform evaluation and quality control.

Applications

FprEN ISO 8367-1 is applicable to a wide range of industries where paper sacks are used, including:

• Food and Beverage: For packaging bulk ingredients such as flour, sugar, or grains, ensuring sacks adhere to standard sizes for automated filling and handling processes.
• Chemicals and Agriculture: Used for seeds, fertilizers, or powdered chemicals, where reliable construction and accurate dimensions are crucial for safe transport and storage.
• Building Materials: Sacks containing products like cement or plaster are standardized for compatibility with packaging and stacking machinery.
• Consumer Goods: Supports consistent branding and printing through defined print position tolerances, aiding in visual quality and traceability.

Accurate dimensional and grammage tolerances help prevent product loss, improve palletization and transport efficiency, and facilitate communication between suppliers and buyers regarding quality and performance expectations.

Related Standards

For full implementation and compliance, several related standards support and complement FprEN ISO 8367-1:2026:

• ISO 536: Paper and board – Determination of grammage
• ISO 6590-1: Packaging – Vocabulary – Part 1: Paper sacks
• ISO 6591-1: Packaging – Dimensions and method of measurement – Part 1: Paper sacks
• ISO 7023: Packaging – Sacks – Method of sampling empty sacks for testing

These standards provide definitions, test methods, and measurement procedures referenced in the dimensional tolerance specifications.

Practical Value

Adhering to FprEN ISO 8367-1 ensures that paper sacks produced across different manufacturers are consistent in dimension and mass, minimizing disruptions in supply chains and packaging operations. This improves efficiency, reduces waste caused by out-of-spec products, and helps companies meet global procurement requirements. By standardizing tolerances, the document enhances customer satisfaction and supports regulatory compliance for paper sack packaging.
