JIS Z 1707 is the Japanese Industrial Standard titled "General Rules of Plastic Films for Food Packaging." It provides a standardized framework for the physical and mechanical properties required of plastic and edible films used in the food industry. GlobalSpec Scope & Application The standard specifies general requirements for both single-layer multi-layer plastic films, primarily focusing on those with a thickness of less than . It is widely cited in research for developing sustainable, biodegradable, and edible food packaging materials.

JIS Z 1707 is the Japanese Industrial Standard for the general rules of plastic films for food packaging . It establishes common requirements for both single-layer and multi-layer plastic films—typically those with a thickness of less than 250 µm—used to protect food products. Key Scope & Application Target Materials : Covers membranous high polymer materials (plastic films). It does not apply to films containing metal foils or paper. Objective : To ensure the safety and mechanical integrity of food packaging, preventing damage during handling or storage. Version : The most recent major update is JIS Z 1707: 2019 . Primary Testing Parameters The standard specifies various physical and mechanical properties that films must meet to be considered compliant: Puncture Resistance : Measures the force required for a specific pin to penetrate the film. This is critical for packaging containing sharp items like bone-in meat or dried fish. Tensile Strength & Elongation : Evaluates the film's ability to stretch and resist breaking under tension. Thickness : Sets general tolerances for film thickness to ensure consistent barrier performance. Gas Barrier Properties : Often referenced for Oxygen Transmission Rate (OTR) to ensure food freshness.

JIS Z 1707 is the Japanese Industrial Standard for Food Wrapping Plastic Films . Because this standard covers a wide variety of materials (from the plastic wrap in your kitchen drawer to heavy-duty industrial packaging), a "good feature" to focus on is how the standard classifies films based on their functional properties and material types. Here is a feature breakdown of JIS Z 1707, highlighting why it is a critical benchmark for food safety and packaging performance.
Feature Focus: The Classification and Performance Requirements of JIS Z 1707 Unlike a simple material specification, JIS Z 1707 acts as a comprehensive performance guide. It ensures that whether you are wrapping a raw fish or a loaf of bread, the film performs specific jobs correctly. 1. Classification by Material (The "Ingredients") One of the strongest features of the standard is how it strictly categorizes films based on their chemical composition. This helps manufacturers and consumers choose the right film for the right application (e.g., microwave safety vs. freezer storage). The standard covers the major plastic substrates: jis z 1707
Polyvinylidene Chloride (PVDC): Often called "saran wrap." Known for high barrier properties (keeping oxygen out) and high cling. Polyethylene (PE): The most common general-purpose wrap. Includes Low-Density (LDPE) and Linear Low-Density (LLDPE). It is flexible and resistant to breaking. Polypropylene (PP): Known for higher heat resistance and stiffness. Polyvinyl Chloride (PVC): Often used for commercial food wrapping (like in supermarkets for meat trays) due to its high clarity and stretch.
2. The "Two-Tier" Strength Classification A distinct feature of JIS Z 1707 is that it does not treat all films the same regarding strength. It divides them into Type 1 and Type 2 based on mechanical properties:
Type 1 (High Strength): These films must meet higher standards for tensile strength and tear resistance. These are designed for heavy items or industrial packaging where the film must not rupture during transport. Type 2 (Standard Strength): These are for general consumer use (household wraps) where ease of tearing and dispensing is prioritized over extreme durability.

3. Critical Performance Testing (The "Pass/Fail" Criteria) To bear the JIS mark, a film must pass a battery of physical tests. This is the core technical feature of the standard:
Gas Permeability (Oxygen & Water Vapor): The standard sets strict limits on how much oxygen and moisture can pass through the film.
Why this matters: For fresh meat, you want high oxygen permeability to keep the meat red. For dried snacks, you want zero oxygen permeability to prevent staleness. JIS Z 1707 quantifies these "Barrier Properties." ScienceDirect
Heat Resistance: The standard tests how the film reacts to high temperatures. This is crucial for labeling "Microwave Safe." If a film deforms or melts at 100°C, it fails specific grades within the standard. Hygiene and Safety (Heavy Metals & Evaporation Residue): Perhaps the most important feature for consumers. JIS Z 1707 mandates strict hygiene testing to ensure that harmful substances from the plastic do not migrate into the food. This includes tests for heavy metals and evaporation residue (ensuring the plastic doesn't leach oils or chemicals when in contact with fatty foods).
4. Dimensional Stability The standard specifies tolerances for thickness and width .
