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.

Related Standards

Implementing ISO 8367-1:2026 often involves reference to other critical standards, including:

• ISO 6590-1: Packaging - Vocabulary - Part 1: Paper sacks; defines terms relevant to this standard.
• ISO 6591-1: Packaging - Dimensions and method of measurement - Part 1: Paper sacks; details uniform measurement techniques.
• ISO 536: Paper and board - Determination of grammage; provides accurate grammage measurement methods.
• ISO 4593: Plastics - Film and sheeting - Determination of thickness by mechanical scanning; applicable for paper sacks with PE film layers.
• ISO 7023: Packaging - Sacks - Method of sampling empty sacks for testing; specifies procedures for selecting samples for quality testing.

Organizations seeking comprehensive compliance are encouraged to consult these related documents, enabling a harmonized approach to packaging quality management.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
