A rubber closure is made of materials obtained by vulcanization (cross-linking) of elastomers with appropriate additives. The elastomers are produced from natural or synthetic substances by polymerization, polyaddition or polycondensation. The nature of the principal components and of the various additives such as vulcanisers, accelerators, stabilizing agents, pigments, etc. depends on the properties required for the finished closure. The following tests are based on the extraction of the plastic material, and it is essential that the designated amount of the plastic be used. Also, the specified surface area must be available for extraction at the required temperature. Environmental-Materials may be tested by standard methods for absorption of water, permeability to water vapour, gases, oils, odours etc. and for characteristics such as light transmission.
The assessment tests plastic packaging or film plastic for recyclability, the risk of product contamination in the packaging after use and the risk of contamination for nonrecyclable “look-a-like” plastic packaging. To help manufacturers ensure plastic packaging is recycled, Virginia-based Trex Co., which makes wood-alternative decking and railing from recycled plastic, is offering free recyclability testing to packaging manufacturers and brand owners. If the packaging passes the test, the companies’ packaging may qualify for the NexTrex recycling program. These documents provide a comprehensive recycling test and test result evaluation criteria for recycling a complete package innovation back into a finished article, instead of a molded plaque as in Critical Guidance. Applications Guidance for HDPE calls for innovations to be recycled back into new HDPE bottles. For PET, Applications Guidance provides for recycling an innovation back into new bottles, sheet, fibers, or strapping. The purpose is to test specific shelf-ready packages for technical compatibility with recycling, including all components of the package. Heat Seal Tester seals the specimen to determine the seal parameters of basic film, laminated films, coating paper and other heat sealing laminated films according to the requirement of relative standards.
Pharmaceutical packaging is the means of providing protection, presentation, identification, information and convenience to encourage compliance with a course of therapy. The commonly used packaging materials are Container, Closure, Carton or Outer and Box. There are various tests for determination of quality, integrity and compatibility of packaging materials. The specification and requirement of quality testing depends on type of pharmaceutical materials used. Containers are tested by many methods of which commonly used test for glass are Crushed glass test, Whole-Container test, Chemical resistance of test, Water Attack Test etc. Closure materials are tested by Transparency test Penetrability Fragmentation test Self seal ability test, Extractive test etc. The requirement of packaging material testing is set according to specification of regulatory agencies like WHO GMP, USFDA and ICH guidelines. Paper products are used in many different industries such as packaging industries, printing industries.

Polyethylene Terephthalate or commonly known as PET is mainly used in industries for making PET bottles and containers. They are the most ideal material to make packaging containers for fragile substances such as chemicals, compounds and food products as they are not reactive and are unable to release any extra residues in the products and compromise their quality. Additionally, the PET is very strong and can withstand different sorts of forces without getting damaged. The PET can be used for making clear bottles and containers, food vessels, and so forth. C630H Heat Seal Tester can be used to determine the optimal heat sealing parameters including dwell time, sealing pressure and sealing temperature for plastic films, flexible composite films, plastic coated paper and other heat-sealable films.

There are many components that can be standardized such as ampules, vials, cartons, labels and leaflets. Rubber plugs and plastic bottles can be standardized with respect to shape and size, varying only in the material of construction. There will be a variety of sizes of components depending on the dosage, but again the same shape could be used but with different dimensions. From the glass containers, alkaline constituents (oxides of sodium, potassium, calcium, aluminum, etc.) are leached into purified water under conditions of elevated temperatures. When the glass is powdered the leaching of alkali can be enhanced in the powdered is critical. The container is crushed and sieved to produce uniform particles of which a definite weight of taken. The control of the particle size and weight of powder ensures that a constant surface area is exposed to the solution. Because all of the glass is examined and extraction is enhanced by the rough surfaces of the particles, this is a severe test, and, if a glass passes, it is unlikely that containers made from it will give trouble while is use. Nevertheless, the technique is tedious and is not applicable to surface treated containers because crushing would expose the alkaline glass below the surface. This test can be used for determining the nature of a glass or for distinguish between two types of glasses, such as neutral or surface – treated.
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.
Hot Tack test methods are sensitive seal-strength measurements and are critical for package validation. Seal-strength data used to measure the performance of medical packages such as sterilized medical devices can be critical to human health if compromised. Manufacturing or converting plastic films which do not meet materials specifications can be catastrophic to the success of a business. Materials produced using improper testing techniques or inadequate testing instrumentation will result in losing key business accounts. Key test measurement parameters such as thickness, hot tack strength, sealing-strength and coefficient of friction must be kept within specifications for the material to perform. Tensile tests are normally performed by a universal testing machine or its equivalent to test for seal strength. A section of the package seal is gripped between jaws and pulled apart at a controlled rate.

Polyvinyl Chloride or PVC is the type of plastic that is supposed to have a higher strength than the HDPE and LDPE as this type of plastic has cross linking molecules although they are not as flexible as the other plastics like HDPE or LDPE. The high strength and low flexibility of the PVC materials make them ideal for use in applications such as Pipes, food trays, wire insulations, clear bottle and so forth. The PVC material is used for application where there is need of less flexibility and more strength. Additionally, PVC can be formulated to have extra ability such a weather resistance, fire resistance and so forth. The low density poly ethylene or LDPE plastics are low density plastic materials that are very flexible and hence are used for making carry bags, polybags, packaging bags and so forth. They can also be used for making plastic films that can be used for many other purposes further.
It is equipped with three individual test dishes and the testing process is completely automatic and conforms to international standards. For example, FSSAI have standards such as IS for checking contact of Polyethylene with foodstuffs, IS for checking Styrene Polymers contact with foodstuffs, and others. These standards are verified using packaging testing equipment by testing plastics which is in contact with food items. The tear-away seal on a single-use container was delaminating instead of cleanly separating from the lip of the container. A customized grip method was created for the Mechanical Test System and containers which had been sealed by different methods were opened by the instrument. The bad seals failed under a lower tensile force than that required to open the good seals. Inconsistent extrusion conditions had caused poor adhesion in regions of the sheets of material used to make the seals. Depending upon the expected stresses and loads of the application any number of tests will be performed upon a plastic material to predict its behavior under those forces.
Consulting & InnovationPackaging Solution Center Home to the most advanced research, testing, and monitoring equipment in the packaging industry. ASTM International is one of the largest standard organizations in the world, composed of expert volunteers. It is a nonprofit organization whose purpose is to develop quality standards that reflect an international consensus for various industries. Ensure that the company meets packaging standards and protocols, industry requirements and the customer’s expectations. The most common option consists of a system that can be attached to the testing machine. There are also strain gauges that do not require constant operation by an operator, which are suitable for ASTM D638 testing in environmental chambers. In other words, the test is performed by applying tensile forces to the sample and measuring how its properties change under extreme tension or stress. To be analytically useful, this dose must be converted to a concentration by dividing it by the daily dose volume. The larger the daily dose volume, the smaller the AET and the lower the concentration at which extractables and leachables must be identified. For example, the safety concern threshold proposed by the PQRI for parenteral drug products is 1.5 µg/day.
Compression testing relates to stacking or crushing of packages, particularly shipping containers. It usually measures of the force required to crush a package, stack of packages, or a unit load. A force-deflection curve used to obtain the peak load or other desired points. Other tests use a constant load and measure the time to failure or to a critical deflection. The puncture resistance test is widely used to make sure that the packaging material is strong enough to survive the transportation conditions and protect the product. The machine is operated by placing the test sample between the holding clamps on a fixture and then it is penetrated using a pendulum which has a pyramid shape. The pendulum is released from an angle of 90° from the surface to be penetrated.
