production improvements as well as a positive environmental impact . The test results from our Film Lab pinpoint stretch film properties as applied to specific conditions. Our materials specialist analyzes the test results to match the best films and the best application of those films for optimal performance and cost savings. In this regard, the ASTM D638 protocol is related to the ISO test, since the purpose of both is to demonstrate the resistance of a plastic to tensile forces. However, in its website, ASTM clarifies that the technical content of both tests is different, and therefore they are not interchangeable. The companies that are required to measure this parameter usually perform just one of the tests, with the ASTM testing method being the favorite in the North American market and area of influence.
A primary purpose of a package is to ensure the safety of a product during transportation and storage. If a product is damaged during this process, then the package has failed to accomplish a primary objective and the customer will either return the product or be unlikely to purchase the product altogether. Modern scratch testers are designed and manufactured to cover a wide range of coating conditions, from soft polymers to exceptionally hard industrial coatings, with thicknesses ranging from the nm to mm level. The material hardness can be explained as the calculation of the amount of resistance exerted by a material against any form of external force. In the paint and plating industry, this particular property of a material can help a researcher in exploring the life expectancy of a particular paint or coating type. It can help in evaluating the fact that would the paint be able to survive a certain working environment or not. In this blog section, we will share details on the role of scratch hardness tester in the evaluation of the resistance to scratch hardness in metals. The nature of the plastic gums can be controlled by its rate of consistency and dissolving rate. The dissolve stream rate of the plastic tars and its quality can be resolved just by utilizing high caliber of testing machines that are profoundly institutionalized and offers exact, institutionalized outcomes.

Fall Dart Impact Testing Machine is used to test the impact resistance of various plastic films and slices, which meets the standards of ASTM D1709. HD-AA520 Pneumatic Single-Wing Drop Tester is suitable for testing the damage of product packaging when it is dropped, and assessing the strength of impact resistance during transportation and handling. The campaign aimed to collect more than 4,000 litres of plastic at the festival. Snack packets, plastic bags and bottle caps were collected and were be taken to Recycling Technologies, which recycles single-use plastics into a raw material used to make new plastic packaging products, the company says. These evaluations are employed when laboratory tests are not yet available or may not be able to predict recycling performance of a package component or innovation. In these cases, it may be desirable to test under regular production scale conditions.
Innovation in plastics and packaging is necessary to maintain a healthy and competitive industry. To support innovators, the APR has developed a variety of laboratory test method documents that can be used to assess the impact of a plastic design feature or component on recycling. APR test methods combine laboratory practices and measurements developed specifically by and for plastic recyclers with standard ASTM tests. The objective of testing is to determine the impact of a design feature on the processability of a package item as well as the ability of post-consumer resin derived from such feedstocks to meet quality specifications for end-use applications. The puncture resistance tester is a highly efficient and exceptional testing instrument that is used for detection of the strength of the packaging materials against any penetration. Anti-puncture properties are important for the best quality of packaging materials so that the products could easily survive the transit. The test is performed on various materials such as thick boards, thin papers and so forth. These testing methods allow packaging materials to be thoroughly known, thereby becoming an essential part of the design process, with sights on obtaining an effective performance and a more sustainable package.
The best laboratory testing device which is used to measure the bursting strength of the papers and packaging products is Bursting Strength Tester. The machine is designed and manufactured as per the standards that are introduced by various standardization authorities such as ASTM, ISO, and many more. To perform the bursting test with the testing machine, take a circular shape of corrugated board sample according to the size of the diaphragm of the instrument. Now place the device on the rubber diaphragm and apply sufficient amount of pressure gradually on the sample until the sample burst.

Extensive research work has been done on the microbial barrier performance of porous medical packaging materials. Conventionally, water bath/bubble leak testing method were used where the packaging is placed into a water bath. Bubbles will be seen coming from the pack in case of any leakage, which is a destructive, subjective test method. PTI’s VeriPac package integrity testing method is a non-destructive alternative to the conventional water bath leak test or bubble leak testing method. VeriPac leak test systems can be utilized for non-destructive package integrity testing for Tyvek and porous packaging. PTI offers inspection systems for package leak testing, seal integrity and container closure integrity testing . Our technologies exclude subjectivity from package testing, and use test methods that conform to ASTM standards.
Leakage tests are generally divided into two parts – vacuum leakage and slant leakage. Environmental Stress Crack Resistance or ESCR Testing is a quite common test for plastic bottles. A plastic container that has undergone such degradation will often crack when exposed to any form of external mechanical forces. ESCR testing for rigid packaging allows manufacturers to see the effect of polymer degradation on containers and how much stress the container can handle after a long shelf life. Qualitest offers an extensive range of advanced plastics testing equipment for testing of plastic pipes, PVC, film, adhesive tape, resins and much more. Glass vials and Ampules – The USPXXII requirements for glass containers are chemical resistance and light transmission. The requirements vary from country to country, but basically testing determines whether the correct type of glass has been used for the manufacture and its suitability for use with pharmaceutical products. Bursting Strength of the materials is a major property that defines the strength and quality of the packaging products.
The most common tests of plastics are tensile tests, compressive tests, flexure tests, shear tests and torsion tests. Tension and compression tests involve the loading of the plastic along its longitudinal axis, but where tension tests pull the ends away from each other compression tests push them together. Flexure tests require the load to be applied to the midsection of the test sample so that it is bent into a “U” or “V” shape with the outside surface experiencing tensile forces and the inside face experiencing compressive forces. Torsion testing simply requires a rotational force or torque to be applied to one end of the sample while the other end is anchored. All of these tests are run until the sample breaks or ruptures with the stress and strain values recorded throughout the duration. Testing a plastic’s mechanical properties determines if it will meet the requirements of the desired application. Plastics are similar to metals in that they can be manufactured or produced using a wide range of procedures and material components in order to achieve the desired material characteristics. Typically the desired characteristics of plastic products are low cost, low weight, high toughness, high elasticity and ductility, and high strength in tension, compression, flexure, torsion and shear. These properties are defined by the chemical makeup of the material components used to produce the plastic and are more specifically dependent upon their molecular weight, hardness, density, and resistance to heat and solvents.
impact solutions through their laboratory have extensive capabilities and experience in plastic testing. Our facility houses a mix of state of the art plastic testing equipment and bespoke designed plastic testing rigs allowing us to undertake a wide range of different test techniques on plastics. Objective laboratory procedures are frequently used to help determine performance. Most common are “jerk testing’’ by modified drop test procedures or use of the constant pull rates of a universal testing machine. Other procedures use a static force by hanging a heavily loaded package for an extended time or even using a centrifuge. The physical properties, and sometimes chemical properties, of the materials need to be communicated to packaging engineers to aid in the design process. Suppliers publish data sheets and other technical communications that include the typical or average relevant physical properties and the test method these are based upon. Other times, additional material and component testing is required by the packager or supplier to better define certain characteristics. Package testing or packaging testing involves the measurement of a characteristic or property involved with packaging. This includes packaging materials, packaging components, primary packages, shipping containers, and unit loads, as well as the associated processes.
Our film material specialist, John Cook, has an extensive background in plastics and film development. We recognize that our work in the Film Lab and our work to get our customers set up with the right films and the right equipment is not a “one and done” project. F2 allows us to fully measure the capabilities of a candidate stretch wrap by determining how it responds to a range of low to high post stretch conditions at a variety of prestretch levels and turntable speeds. Film tension is developed by slowing the film output of the stretch carriage relative to the speed of the turntable. The goal of our Film Lab is to gather data, utilize the knowledge and experience of our film technicians, analyze the results, and make recommendations that match the best film to a particular application. Based on the data gathered during the audit, alternate films are tested in the lab tofind opportunities for a more optimal filmfor the particular application. Once we’ve determined the best films to use in your application, we follow up with training, monitoring, and technical service.
Plastics are synthetic or semi synthetic viscoelastic materials composed of organic polymers and organic or synthetic additives. The behavior of plastics under stress depends on the length of time they are exposed to the stress and the temperature the exposure occurs. The applications for plastic materials are broad because the mechanical properties of plastics are defined by their molecular makeup which may be customized to meet the requirements of the desired application. The more common forms of plastics and their applications are styrene foam or Styrofoam which is used as insulation and packaging, PVC which is used in plumbing and nylon which is a flexible yet strong material used in the clothing industry. Thickness is an important property of a packaging material and critical for other mechanical properties, such as permeability, tensile strength, impact resistance, etc. Besides, it is an efficient way to reduce production cost by controlling material thickness within reasonable range.
