ISO 8351-1:1994

Overview

ISO 8351-1:1994 is an international standard developed by the International Organization for Standardization (ISO) that specifies a comprehensive method for defining the characteristics of paper sacks during the ordering process. This standard provides a detailed checklist to ensure that all relevant details of paper sack construction and design are clearly communicated between customers and manufacturers. Notably, ISO 8351-1:1994 focuses solely on descriptive information and does not cover quantitative performance requirements. The standard is primarily intended to apply to paper sack types as defined in ISO 6590-1 and is a crucial resource for those involved in specifying, ordering, or manufacturing paper packaging.

Key Topics

ISO 8351-1:1994 covers a wide range of ordering specifications and descriptive criteria for paper sacks, including:

• Sack Type: Open-mouth (e.g., sewn flat, sewn gusseted, pasted flat hexagonal-bottom) and valved (closed-mouth) varieties.
• Tube Type: Features such as flush-cut, gusset, stepped-end, and notched-end options.
• Dimensions: Standardized measurement points such as length, width, gusset width, valve width and length, and bottom dimensions according to ISO 6591-1.
• Material Specifications: Details on each ply’s type, grammage, thickness, surface treatment, and film characteristics for thermoplastic linings.
• Closures and Seams: Specifications for sewn closures (type of stitch, thread, and filter cord), pasted closure types, and longitudinal seams.
• Valve and Sleeve Details: Incorporates aspects like valve type, location, material, and sleeve construction.
• Additional Features: Includes bottom patches and caps, adhesive types, sewing patterns, printing requirements, and packaging methods.
• Documentation: Requirements for labeling, paperwork, and special delivery instructions.

This checklist approach ensures that all functional and aesthetic aspects are addressed in the specification, facilitating clear communication and minimizing errors during procurement and production.

Applications

ISO 8351-1:1994 is widely used in the packaging industry, particularly by:

• Manufacturers who produce industrial and commercial paper sacks
• Purchasing managers who need to communicate precise paper sack requirements to suppliers
• Quality control teams responsible for verifying that received sacks meet the specifications agreed upon at the time of order
• Logistics and packaging engineers working in sectors such as food, chemicals, agriculture, and retail

By standardizing the method of specification, ISO 8351-1:1994 increases efficiency, helps reduce miscommunication, and supports the consistent supply of paper sacks that meet client expectations and industry norms. It also assists in drafting technical data sheets and orders (sales documents) that clearly outline all necessary details for paper sack procurement.

Related Standards

For a comprehensive approach to packaging and sack specification, the following related standards should also be considered:

• ISO 6590-1: Packaging - Sacks - Vocabulary and types - Part 1: Paper sacks
• ISO 6591-1: Packaging - Sacks - Description and method of measurement - Empty paper sacks
• ISO 8351-2: Packaging - Method of specification for sacks - Part 2: Sacks made from thermoplastic flexible film

These related ISO packaging standards complement ISO 8351-1:1994, supporting organizations in achieving best practices in paper sack specification, manufacturing, and supply chain management.
