Overview
ISO/FDIS 8367-1:2026 is an international standard developed by ISO that specifies dimensional tolerances for general purpose paper sacks. This document is part of the ISO 8367 series and provides clear guidance on acceptable variations in the size and material quality of paper sacks, supporting consistency in the manufacture and quality control of packaging materials. By detailing tolerance ranges for key measurements such as sack length, width, grammage, and valve openings, this standard helps manufacturers, suppliers, and users ensure reliable packaging performance and facilitate compliance throughout the supply chain.
Key Topics
- Dimensional tolerances: Defines permitted deviations for all critical dimensions, such as sack length, width, bottom width, gusset width, and circumference, ensuring each sack meets strict size requirements.
- Paper grammage: Establishes limits on the weight of paper per square meter, both for individual plies and combined total, which impacts sack strength and durability.
- Sampling and measurement: References standardized methods for sampling sacks for testing and for measuring dimensions and grammage to guarantee repeatability and compliance across batches.
- Valve and sleeve tolerances: Specifies allowed variations in the components important for filling and sealing the sacks, such as the width and length of valve openings and sleeves.
- Printing tolerances: Includes permissible deviations in print position to support branding and information clarity without affecting sack performance.
Applications
ISO/FDIS 8367-1:2026 is essential for various stakeholders in the packaging industry:
- Manufacturers: Ensures paper sacks produced meet international criteria for dimensions and material quality, enhancing product consistency, performance, and market acceptance.
- Distributors and suppliers: Provides a clear framework for quality assurance checks, minimizing the risk of non-compliant shipments and reducing disputes between trading partners.
- Buyers and end-users: Enables informed purchasing decisions by referencing a globally recognized standard, thereby guaranteeing the packaging is fit for purpose and reliable in transport and storage.
- Regulators and auditors: Offers a benchmark for verifying contractual and regulatory requirements in procurement and inspection processes.
This standard is particularly relevant for sectors such as food processing, agriculture, construction, and any industries relying on bulk packaging and shipment of dry goods in paper sacks.
Related Standards
To ensure comprehensive compliance and consistent packaging quality, ISO/FDIS 8367-1:2026 should be used alongside the following key standards:
- ISO 6590-1: Packaging - Vocabulary - Part 1: Paper sacks. Provides essential terms and definitions.
- ISO 6591-1: Packaging - Dimensions and method of measurement - Part 1: Paper sacks. Details methods for assessing physical sack parameters.
- ISO 536: Paper and board - Determination of grammage. Guides measurement of paper weight, crucial for sack strength.
- ISO 7023: Packaging - Sacks - Method of sampling empty sacks for testing. Covers procedures for representative quality sampling.
- ISO 4593: Plastics - Film and sheeting - Determination of thickness by mechanical scanning. Relevant if sacks contain a plastic (PE) liner or component.
These companion standards address related aspects of sack packaging production, measurement, and quality control, ensuring end-to-end reliability for manufacturers and users.
Keywords: ISO 8367-1, paper sacks, packaging dimensional tolerances, sack grammage, packaging standards, ISO packaging, paper sack manufacturing, quality control, packaging compliance, international packaging standards.
