In today’s competitive manufacturing environment, maintaining product quality and reliability is more important than ever. Products often travel long distances and pass through multiple handling stages before reaching customers. During transportation, Plastic & Polymer Testing Instruments materials may face impacts, compression, and environmental stress. To ensure that products remain safe and undamaged, manufacturers rely on advanced testing equipment. Among the most widely used instruments are the Drop Tester – Motorized, Box Compression Tester – Computerized, and Melt Flow Index Tester – Digital and Computerized models.

These testing machines help industries analyze the strength, durability, and performance of packaging materials and plastic products. By using reliable testing equipment, companies can improve product quality, reduce damage during transportation, and ensure compliance with international quality standards.

Importance of Quality Testing in Manufacturing

Quality testing plays a critical role in modern manufacturing processes. Packaging materials and plastic products must meet strict performance requirements to ensure safety and durability. Without proper testing, products may fail during shipping or storage, leading to customer dissatisfaction and financial losses.

Poly Films and Laminates Testing Instruments allow manufacturers to simulate real-world conditions and measure how materials behave under stress. These machines provide accurate data that helps improve product design, material selection, and packaging efficiency. As industries continue to grow and competition increases, quality testing becomes an essential part of production and quality assurance systems.

Drop Tester – Motorized

The Drop Tester Motorized is designed to evaluate the ability of packaging materials to withstand sudden impacts. During transportation and handling, packages may accidentally fall from various heights. If the packaging is not strong enough, the product inside may be damaged.

A drop tester simulates these situations by dropping the packaged product from a predetermined height onto a solid surface. This test helps determine whether the packaging can effectively protect the product during handling and shipping.

Key Features

Motorized lifting mechanism for precise height adjustment

Adjustable drop height for different testing conditions

Strong platform for safe and controlled testing

High accuracy and repeatability of results

User-friendly operation

Benefits of Drop Testing

Supports quality control and packaging standards

Industries such as electronics, consumer goods, pharmaceuticals, and logistics commonly use drop testers to ensure packaging reliability.

Box Compression Tester – Computerized

The Box Compression Tester Computerized is used to measure the compressive strength of corrugated boxes and packaging containers. During storage and transportation, boxes are often stacked on top of one another. If the packaging cannot handle the pressure, the boxes may collapse and damage the products inside.

This testing machine evaluates the load-bearing capacity of packaging boxes by applying pressure until the box deforms or collapses.

Key Features

Computerized control system for precise testing

High-precision load cell for accurate force measurement

Digital display for easy monitoring

Durable and strong testing structure

Software integration for data analysis and reporting

Testing Procedure

During the test, the box is placed between two compression plates. The machine gradually applies force until the box begins to deform. The maximum load applied before failure is recorded and used to determine the strength of the packaging material.

In the modern plastics and polymer industry, product quality, processing efficiency, and material consistency are closely interconnected. One of the most important parameters used to evaluate thermoplastic materials is the Melt Flow Index (MFI). Accurate measurement of MFI helps manufacturers ensure that raw materials perform consistently during processing and deliver the desired end-product properties. To achieve this level of accuracy and repeatability, advanced testing equipment such as the Melt Flow Index Tester – Digital Model from Pacorr plays a crucial role.

This article provides a comprehensive overview of melt flow index testing, the functionality of a digital MFI tester, its applications, and why Pacorr’s solution is trusted by industries worldwide.

What Is Melt Flow Index (MFI)?

The Melt Flow Index, also known as Melt Flow Rate (MFR), measures the ease with which a thermoplastic polymer flows when melted under specific conditions of temperature and load. It is expressed as the weight of polymer (in grams) that flows through a standardized die in ten minutes.

MFI is directly related to the molecular weight and viscosity of the polymer:

High MFI indicates lower viscosity and easier flow

Low MFI indicates higher viscosity and stronger molecular chains

This property significantly affects how the material behaves during processes such as extrusion, injection molding, and blow molding.

Importance of Melt Flow Index Testing

MFI testing is a vital quality control tool across the polymer supply chain. It helps manufacturers:

Verify incoming raw material quality

Maintain consistency between production batches

Select suitable materials for specific processing techniques

Reduce processing defects and material wastage

Ensure compliance with international standards

Without accurate melt flow data, even high-quality polymers can result in defective products or inefficient processing.
