ISO 8367-1:2026 PDF

Overview

ISO 8367-1:2026 is an authoritative international standard developed by ISO for the packaging industry. This standard defines precise dimensional tolerances for general purpose paper sacks intended for a wide range of packaging applications. It ensures that manufacturers, suppliers, and users of paper sacks adhere to clearly established requirements for dimensions and grammage, fostering quality, interchangeability, and consistency in production.

This document forms Part 1 of the ISO 8367 series and specifically addresses paper sacks, as further defined in ISO 6590-1. Compliance with ISO 8367-1:2026 is essential for organizations seeking to meet internationally recognized quality benchmarks in packaging.

Key Topics

• Dimensional tolerances: Standardizes acceptable size variations in length, width, gusset, valve openings, and other critical features of paper sacks.
• Measurement methods: References authoritative standards for measurement-including ISO 6591-1 for dimensions, ISO 536 for grammage, and ISO 4593 for PE film thickness.
• Paper grammage tolerances: Details two compliance routes:
  • Each paper ply’s grammage within ±4% of nominal value
  • Total plies’ grammage within ±4% of nominal value, with individual plies not deviating by more than ±15 g/m².
• Test procedures: Specifies the use of ISO 7023 for sampling paper sacks for conformity testing.
• Updates and revisions: Reflects significant updates, including clarified grammage tolerances and enhanced test reporting.

Applications

ISO 8367-1:2026 is vital wherever general purpose paper sacks are manufactured, filled, transported, or purchased. Its applications include:

• Packaging industry: Ensures reliable quality and performance for sacks used in food, chemicals, construction, and agricultural goods.
• Manufacturing and quality control: Provides manufacturers with objective criteria for production and inspection, reducing variation and minimizing rejects.
• Procurement and supply chain: Facilitates communication of requirements between buyers and suppliers, supporting seamless sourcing across borders.
• Regulatory compliance: Supports conformity with trade and safety regulations by providing an internationally aligned benchmark.
• Product development: Assists packaging engineers in designing sack products that are compatible with automated filling equipment and transport logistics.

By adhering to this standard, organizations benefit from improved efficiency, reduced production errors, and increased customer satisfaction due to standardized measurement and tolerance practices.
