The reagent for the pinhole test, "methylene blue solution," is already prepared, so it is convenient.

You can use it for verification tests such as the physical strength of containers and the presence of leaks! It has been prepared according to the composition of the official method, so you can use it for testing as is!

The "pinhole test reagent" is a reagent used in the pinhole test, which is one of the strength tests for containers. This test is conducted based on the Food Sanitation Act, using the specified "methylene blue test solution" to check for the presence of pinholes in the container. The "methylene blue test solution for pinhole testing" is prepared according to the official method composition and can be used directly for testing. Additionally, this methylene blue test solution can also be utilized for verification tests of the physical strength of container packaging, such as "compression resistance tests" and "connection resistance to reduced pressure tests," as well as checking for leaks. It is highly recommended for quality control of containers and inspections in food manufacturing settings. 【Packaging containers subject to the pinhole test】 1. Among the packaging containers for soft drinks, those that use materials other than metal for sealing the opening of metal containers, as well as those made of synthetic resin, synthetic resin-coated paper, synthetic resin-coated aluminum foil, and combination packaging. 2. Among the packaging containers for dairy products, those made of polyethylene for milk, polyethylene-coated paper, and combination packaging, as well as those made of synthetic resin for dairy products, synthetic resin-coated paper, synthetic resin-coated aluminum foil, and combination packaging.

basic information

Based on the Food Sanitation Act, standards and testing methods for determining the suitability of materials and containers used for food and additives are established according to their material and purpose. The "pinhole test" is one of the strength tests for containers, which checks for the presence of pinholes in the container using the specified "methylene blue test solution." The "methylene blue test solution for pinhole testing" is prepared according to the official method composition and can be used directly for testing. Additionally, this methylene blue test solution can also be utilized for verification tests of the physical strength of container packaging, such as "compression resistance tests" and "connection resistance to decompression tests," to check for leaks. Please make use of it for quality control of containers and inspections in food manufacturing settings.
