Overview
ISO 9884-1:1994 – Tea sacks - Specification - Part 1: Reference sack for palletized and containerized transport of tea is an international standard developed by the International Organization for Standardization (ISO). This document specifies the minimum materials, construction characteristics, and dimensions for a "reference sack" used in the efficient and effective palletized and containerized transport of tea. It addresses the industry's shift from traditional plywood tea chests to more available and cost-effective packaging materials, ensuring product safety, quality, and transportation efficiency throughout the global supply chain.
Key Topics
- Reference Sack Design: Details the design of a valve-pasted, flat, hexagonal-ended sack constructed from multiple plies of kraft paper, including an inner aluminium-coated barrier, suitable for use with pallets and shipping containers.
- Materials Specification: Sets standards for the use of either normal kraft paper or extensible kraft paper, bonded with polyethylene and featuring an aluminium moisture and odour barrier to protect tea from external detriments like moisture, taint, and physical damage during transit.
- Dimensional Requirements: Establishes standard dimensions for both empty and filled sacks to ensure compatibility with standard four-way entry pallets and ISO freight containers, facilitating stacking, loading, and transport efficiencies.
- Mechanical Strength: Specifies strength requirements such as tensile strength, stretching capability, and bursting index to guarantee sack integrity under the stresses of palletization, containerization, shipping, and unloading.
- Testing Methods: Outlines standardized testing procedures for key parameters like grammage, tensile strength, and moisture barrier effectiveness, referencing globally recognized ISO methods to ensure consistency and reliability.
Applications
- International Tea Trade: Assists tea producers, exporters, logistics providers, and importers in selecting and evaluating bulk packaging solutions that meet standardized requirements, reducing the risk of product damage and contamination.
- Palletized and Containerized Shipping: Ensures sacks are compatible with both palletized unit loads and global freight containers, optimizing space utilization and compliance with international packaging norms.
- Quality Assurance: Provides a benchmark for sack manufacturers and users by defining reference performance, making it easier to test alternative sack constructions against an internationally recognized model.
- Supply Chain Efficiency: Enhances supply chain transparency and reliability by standardizing sack dimensions and structure, facilitating automated handling, and minimizing freight rejections due to non-compliance.
- Sourcing and Procurement: Simplifies sourcing by providing clear, measurable specifications for suppliers, helping buyers ensure packaging meets international expectations.
