How do I check the quality of packaging boxes against bursting?

Testing the bursting strength of materials is essential for determining the quality and safety of a product. The bursting strength is a measure of how much weight, pressure or force a material can withstand before it ruptures, breaks, or tears apart.

Thus, testing the quality of boxes against bursting is considered to be an important factor to check the durability of materials against bursting. Thus, we at Presto have designed high-quality lab testing equipment that is used to test the bursting strength of boxes and ensure that quality materials are delivered to the customers. The Presto bursting strength tester is considered to be one of the high-quality laboratory testing equipment that is used to test the bursting strength of materials and ensures that the quality of products will be delivered to the customers.

This quality testing equipment will ensure that the packaging boxes will accurately be delivered without the hassle of being burst in between shipping. In this blog, we are going to provide you with information about the Presto bursting strength tester and how this quality testing equipment is useful in testing the bursting strength of materials.

What is bursting strength and why it should be calculated?

If you are a corrugated box manufacturer then facing product rejections due to poor quality of corrugated boxes is one of the critical challenges you must be experiencing. When the product will not reach the desired destinations, then the manufacturers find it challenging to stay as per customer expectations.

This will not affect their reputation but also lead to losses. Thus, besides testing different factors of quality, the bursting strength is one of the crucial factors to consider while determining the quality of boxes. We at Presto have designed high-quality lab testing equipment known as burst testing equipment that is used to test the ability of boxes against bursting.

This quality testing equipment will assess the durability of materials against bursting. It consists of an electric motor with a speed regulator and gearbox fitted on a heavy cast iron base stand having leveling screws at its four corners.

The digital model of this testing instrument has been equipped with various advanced features that make it easy to use. A bursting strength tester is the most widely used machine in industries where raw materials like paper, cardboard, cloth, rexine, leather, foil, etc. are used. You can easily beat the problem of burst boxes by testing their bursting strength.

Now, let us discuss a brief about this quality testing equipment.

All about Presto bursting strength tester

The bursting strength of packaging materials like corrugated boxes or fiberboards is important to be considered because it will directly affect how well the material will be protected against the rigors of shipping. Thus, we at Presto have designed high-quality lab testing equipment that is used to test how the material will be able to withstand the bursting strength of materials.

The main purpose of the Presto bursting strength tester is to determine the durability of materials by determining their bursting properties under multi-directional force.

It comes with some low-cost consumables like diaphragm and glycerin which can be replaced without any hassle in case of wear and tear. The life of the diaphragm depends on the number of tests performed. You can also read about the significance of the bursting strength tester of corrugated boxes.

Now, let us discuss the features and technical specifications of this quality testing equipment.

Features of Presto digital bursting strength tester

The bursting strength of packaging material is important as it will directly impact the strength of corrugated boxes. Packages that are subject to high levels of pressure (such as those shipped via airfreight) need to be made from materials with high bursting strengths in order to prevent them from being damaged in transit.
