Checking the tightness of packages allows companies to detect defects and holes that could affect the quality and shelf-life of products. Tightness testers examine the ability of packaging materials and seals to withstand pressure and stress during transportation. At Seal-Check, we have high-tech package testers that evaluate and gauge the strength and resistance of different types of product containers. Our tightness testing process involves comprehensive laboratory experiments and careful human evaluations that will ensure the quality of your packaging. 

Why Is Checking Package Tightness Mandatory?

Package tightness checking guarantees quality packaging while reducing logistics costs. Product manufacturers must test their product containers at the design and production stages. The multi-stage package tightness testing procedures let you know how a product’s packaging will perform when exposed to different demands and conditions. All testing procedures must adhere to rigorous industry standards. Package testing companies don’t always follow the same guidelines, but these are the fundamental checking process for tightness.

Stress Response

The first step to confirming package tightness is examining how well it responds to real-world stress. A good product packaging must tolerate mechanical stresses during transportation, including drops, stacking pressure, vibrations, and impact shocks. Manufacturers also check if product containers are durable enough to withstand climatic pressures during transport and warehousing.

Ability to Withstand Compression

The compression testing process checks the product package’s ability to endure external pressures. This tightness testing stage involves pressing the packaging between two parallel plates to check for damage and deformation impacts on the product or the container itself. Stacks of products are a common sight during transportation to make the best use of space, so knowing that your package can withstand compression is very advantageous.

Extreme Weather Conditions

At Seal-Check, we have high-end packaging tightness testers and package leak detectors to conduct in-depth evaluations to determine how well a product responds to different climatic conditions. Substandard product containers will deteriorate, deform or become moldy when exposed to certain humid or hot temperatures. We place packages in controlled atmosphere chambers for a certain period to examine their ability to endure demanding weather conditions. Our engineering ensures that these chambers can simulate low or high temperatures and alternating humidity levels.


Road, water, and air transportation are common for every product in the supply chain. Vehicles and airplanes expose these to certain vibration levels, which can affect the tightness of the packages. To minimize the damage vibrations effect, manufacturers must add robust waterproofing and a sealing system to their product containers. We at Seal-Check use the most advanced vibration testing tools to extensively examine packaging performance when exposed to areas with high vibrations.

Impact Resistance

The next stage in checking the tightness of packaging is evaluating its ability to resist impacts. Impact resistance testing checks how well a package will perform once dropped from a certain height. It also examines how it will respond when pushed or pulled against a surface with high force. Most impact resistance checking tests only rely on the stipulated conditions to examine a packaging’s tightness.


Product packages should be able to resist punctures as they will be exposed to conditions that may trigger these. So many issues in product packaging can cause holes, including sharp trailer edges, other products, or corners of poorly kept containers. Ultra-modern puncture resistance testers examine how much energy it will require to create holes in product packaging.
