Overview
ISO 8367-2:1993 specifies the dimensional tolerances for general purpose sacks made from thermoplastic flexible film. Developed by the International Organization for Standardization (ISO), this standard provides manufacturers, quality inspectors, and packaging professionals with a reliable framework for ensuring consistency and quality in sack production. The standard covers essential dimensions, describes measurement methods, and promotes compatibility in the global packaging industry.
Key Topics
ISO 8367-2:1993 defines the allowable variations (tolerances) for the main dimensions of thermoplastic flexible film sacks. Key parameters include:
- Thickness of plies: Ensuring uniform film thickness for durability and protection.
- Length and width of sack: Standardizing overall size for storage and transport efficiency.
- Width of gusset: Controlling side expansion for volume and stability.
- Circumference of sack with gussets: Standardizing fit and compatibility.
- Width of bottom: Ensuring base stability.
- Width and position of valve: Important for filling, sealing, and emptying processes.
- Leading edge and length of valve sleeve: Facilitating efficient product filling and minimizing spillage.
- Print position on sack: Ensuring branding and labeling are correctly placed and legible.
All measurements and tolerances are defined to promote interoperability and minimize errors during manufacturing and use.
Applications
ISO 8367-2:1993 is essential for professionals involved in the design, manufacture, and quality control of packaging using thermoplastic flexible film sacks. Practical applications include:
- Manufacturing control: Ensures that sacks meet specified tolerances, resulting in fewer defects and more consistent production.
- Quality assurance: Provides a benchmark for inspection processes, reducing disputes over dimensional conformity.
- Supply chain optimization: Harmonized sack dimensions simplify logistics, stacking, and transportation, contributing to cost savings.
- Regulatory compliance: Assists companies in demonstrating adherence to international packaging quality standards.
- Customer trust: Consistent packaging dimensions enhance consumer and business partner confidence in the product.
Industries such as food processing, agriculture, chemicals, construction, and retail can benefit substantially from implementing this standard.
