Main packaging performance indicators of plastic materials
(1) Main protection performance and its indicators
1. Barrier; 2. Mechanical properties; 3. Stability.
1. Barrier: mainly includes anti-light transmission, gas barrier, moisture, water permeability, etc.
(l) Transmittance: %.
(2) Air permeability and air permeability coefficient: the amount of gas permeating through a 1m2 area for 24 hours; the gas permeating the material per unit area and thickness under the unit pressure difference per unit time
(3) Moisture permeability and moisture permeability coefficient: the amount of water vapor permeating through an area of 1m2 for 24 hours;
steam quality.
(4) Water permeability and water permeability coefficient: the mass of water permeating an area of 1m2 for 24 hours; the water permeating the material per unit area and thickness under the unit pressure difference per unit time
2. Mechanical properties: Under the action of external force, the material exhibits the performance of resisting external force without deformation and damage.
(1) Rigidity: The property of a material to resist external force without elastic deformation is called rigidity.
(2) Tensile strength, compressive strength, flexural strength:
When the material is not damaged under the slow action of tensile, compressive and bending forces, the maximum force that the unit stressed section can bear is the tensile, compressive, and flexural strength of the material, respectively.
(3) Bursting strength: The minimum internal compressive stress applied to rupture the plastic film bag.
(4) Impact strength: The material's ability to resist impact force without damage.
(5) Tear strength: The property of the material to tear continuously along the notch.
(6) Puncture strength: the minimum force required for the material to be pierced by a sharp object.
3. Stability: the ability of the material to resist the influence of environmental factors (temperature, medium, light, etc.) and maintain its original performance. It mainly includes high temperature resistance, low temperature resistance, oil resistance, aging resistance, etc.

In today's ever-evolving packaging environment, sometimes evaluating against a standard isn't enough. GBPI's global team of experts can work with you to create custom standards for the packaging you're designing, for sourcing your products, or to ensure products arrive on your store shelves intact.
