The plastic testing instruments help in testing the quality of the plastic products with great accuracy and hence ensure the best quality of products. There are many different types of plastics that are in used in both industrial as well as domestic fronts. W3/062 is based on cup method to measure water vapor transmission rate of plastic films, foils and finished packages. It has Six independent testing cells and can be easily connected with 9 satellite systems. These standards help to identify characteristics such as chemical content, acidity or alkalinity, tensile breaking strength, peel adhesion, and water, oil, and tear resistance among others. Modern and advanced testing technology for measuring the scratch resistance can supply an accurate increasing force while the testing sample is dragged against a durable, diamond-tipped stylus. These types of Scratch testers can additionally be equipped with sensors to monitor penetration depth, lateral friction force, and acoustic emission. This is a world of reporting critical coating failures as “12.3 N” rather than “Yes”! This modification opens the door to highly advanced coating process and quality assurance to a degree that can never be imagined. Moreover, the distribution of critical failure loads across individual samples or batches provides an excellent measure of the homogeneity or repeatability of the production process, respectively.
The name and lot number of the product being handled should be displayed at each packaging station or line. The nozzle must have a good interference fit into the bottle and allow one drop at a time deliver through the hole in the nozzle when inverted, but must not leak from the fitted position. Critical – unacceptable at any level, e.g., rogue printed items in a delivery, incorrect printing of data such as the product name or concentration, insects in the bottle etc. c) Product stability- it is unlikely that a compatibility problem, particularly with the film coated tablet, will occur, although it is necessary to check up full life of the product. There is possibility that either the smell or taste of tablets will be affected. b) Light transmission- this test is to determine the effect of light passing through the bottle wall on the product stability and appearance. The bottle wall thickness can have a significant effect on the results obtained. It prevents the deterioration of product from the effects of environment such as moisture, oxygen, or carbon dioxide. The closure is normally the most vulnerable and critical component of a container as far as stability and compatibility with the product is concerned.
Headspace GC-MS was used to perform the odor analysis and find the composition of volatiles in the atmosphere around the product. The results showed that the packaging material was the same between good and bad samples. The gas sample from the smelly product had volatile compounds that are evidence of lipid oxidation. The atmospheric modification step was not thoroughly purging the container of air during packaging of the problematic batch.

This test is designed to evaluate responses to the instillation of extracts of material under examination in the eye of a rabbit. 2 Systemic injection test; Intracutaneous test Comply with the tests described under Plastic containers for Parenteral Preparations. Comply with the tests described under Plastic containers for Non-parenteral Preparations. The principle involved in the powdered glass test in estimate the amount of alkali leached form the glass powder. The amount of acid that is necessary to neutralize the released alkali is specified in the pharmacopoeia. In this test, surface area does not increase as much as volume with the increase in container size, consequently, the small sized containers are more attacked by the leaching of the alkali from the surface. Glass is a common material to be used in either no sterile or sterile liquid dosage forms. Hence, a limit test for alkalinity is to be performed before using it for a particular product. Soda-lime-silica glass is a silica glass containing alkali metal oxides, mainly sodium oxide and alkaline earth oxides, mainly calcium oxide.
The testing matrix would primarily depend on the composition of the packaging system. According to USP, “This testing generates a chemical safety assessment of a packaging system, based on risk-based testing.” However, if a material is well characterized and has data available, this step can be bypassed.

This offers our customers a significant savings in terms of cost and also has benefits in terms of secure load containment , 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.
In this case, it is fundamental to ensure that the samples undergo the same processes. There is also, however, the option of including different sample preparation methods as part of the comparison test method. Moreover, parenteral formulations are chemically complex and diverse, thereby having variable and potentially aggressive “leaching powers” and presenting potentially great challenges with respect to their analytical characterization. Furthermore, the conditions of contact between a parenteral and its packaging can be relatively harsh, increasing the likelihood of leaching. For example, packaged parenterals may be subjected to high energy sterilization or may have relatively long shelf lives. In addition to the high risk associated with a parenteral and its packaging, parenterals and their packaging have certain unique features which complicate the chemical and biological safety assessment. First, parenteral packaging is compositionally diverse, consisting of a multitude of materials of construction including elastomers, glass, stainless steel, LDPE, HDPE, PP, PETG, COC, COP, PVC, multilayer films, etc. As such materials will have varied and potentially complex compositions, the universe of potential foreign drug product impurities is large and chemically diverse. Polymers and polymer-based composites represent the largest and fastest-growing area of materials for engineering and other structurally-demanding applications.
Critical devices – a critical device is any device that unless it is working correctly, could affect product quality. Each device must be identified and calibrated or challenge on a regular basis to ensure that it is working within specified limits. Chemical testing- The majority of chemical testing is required on primary components. All aspects of a pack development that may give rise to quality problems must be identified and minimized by good design. Rubber closures are used in a number of formulations and consequently different closures possess different properties. The closures chosen for use with a particular preparation should be such that the components of the preparation in contact with the closure are not adsorbed onto the surface of the closure to an extent sufficient to affect the product adversely. The containers are simply filled with the test solution and exposed to the test conditions. Glassware may pass the whole container test more easily because the surface layer of a container is smooth and less reactive.

As film tension is increased during the testing cycles, the corner plate will eventually puncture the film . High performance films will accept this puncture but the initial hole initiated in the film will not grow or propagate. As the film tension increases during subsequent test cycles, the hole will increase in size, eventually leading to our proscribed failure level (approximately 4″ tear) or actual breaking of the film web. This is the test we use to determine the maximum film tension any individual film can withstand at a given prestretch level and turntable speed. In turn, this allows us to predict the maximum load containment available from a given film. This is essential when obtaining accurate results while performing the ASTM D638 method since the thickness of the sample will change. Likewise, the machines offer customization options which include adding more security measures, as well as an option that allows for the process to be automated. Automated systems take care of measuring the sample, loading it, testing it and removing it.
Paper and packaging testing instruments are vastly used in a variety of industries where paper and paper products are used. There are many industries that are involved in dealing with paper and paper products. Along with that there are packaging industries, printing and publications industries, news paper industries and so forth. The products that manufactured in these products are further used by many different industrial and domestic applications for a variety of purposes. According to the application, there are different requirements for different products when they are being used. One of the most important usages of paper products is in the packaging industries. The paper products are used for packaging and wrapping of a vast variety of products and provide protection to them from the potential threats from the external factors.
Along with that, the paper products are also used in many domestic fronts for example, the tissue paper, copier paper, newspaper, napkins, cardboards & paperboards and so forth. Some of the paper products such as baking paper and butter paper are used in the food industries as well. As the paper products are used for so many industries, it is essential that the quality of these products is thoroughly checked so that they could serve their purpose well without any damage or the failure. Properties of the paper such as their strength, thickness, colour and so forth are the properties that must be tested in order to ensure the best quality of paper is provided for the users. Most of the paper used in the industries today is the recycled paper for the environmental purposes. Now the recycling of paper can have a great impact on the properties such as molecular bond, colour, pigmentation and so forth.
For many clients, the sample that is submitted is the actual product or the portion of the product that contains the plastic. Testing food packaging to make sure it doesn’t contaminate food or break down when frozen or microwaved — but will break down in a landfill. The right packaging also needs to ensure the safe delivery of the product through the supply chain. We report news, gather data and deliver timely information that provides our readers with a competitive advantage. But it is not uncommon for MRF operators to have to shut down their lines completely several times each day to allow workers to go into the machinery and cut out flexible plastics have wound themselves around sortation equipment. While collection programs differ significantly from location to location, most customers have long been able to put in their recycled PET and high density polyethylene containers into curbside mix.
