Lab Equipment

Polymer Packaging maintains the following equipment in our onsite lab/R&D facility

DSC (Differential Scanning Calorimeter) Testing
The DSC is utilized in all stages of manufacturing from quality assurance and production through to research and development. It is used to help identify exact chemical structures and structures.

FTIR/ATR (Fourier Transform Infared/Acutal Transforma Infared) Testing
Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high-spectral-resolution data over a wide spectral range. It identifies the exact chemical structure (based on the periodic table) of a product. It is particularly valuable in reverse engineering a product during the R&D stage.

(ATR) Attenuated Total Reflection testing is mainly used for studying polymer surfaces, The ATR is a special accessory unit which can be used with Fourier transform infrared (FTIR) spectrometers.

Microscopic Structural Analysis Testing
Microscopy analysis helps to determine the structure and properties of materials, composites and products. Microscopy magnification can be used to obtain chemical and physical information about a polymer’s structural features. This is essential as it provides insight which can be related to the performance of the material. Our experts use microscopy to support new material research and development, to process and property optimization, to investigate polymer morphology and microstructure, composites structure, failure analysis, degradation and a wide array of problem solving.

Haze Meter Testing
Haze is cloudiness of a product caused by the scattering of light. Light may be scattered by particles suspended in the material, such as pigment particles or contaminants, or by an imperfect surface cause by dirt or a fine texture. Haze is an important appearance attribute which can be quantified and used to assess the quality of flexible packaging film. With a single pass of the light source through your material, the system measures light diffusely scattered for transparent or slightly translucent materials.

OTR/MVTR (Oxygen Transmission Rate/Moisture Vapor Transmission Rate) Testing
Oxygen Transmission Rate/OTR Tester is used in evaluating plastic films, sheeting & bags. Oxygen transmission rate (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It relates to the permeation of oxygen through packaging, moisture vapor transmission rate and food safety/spoilage.

Hot tack/SIT Seal Initiation Temperature) Testing
PPI evaluates product seal strengths by performing Hot tack testing according ASTM F1921 (method B). Hot tack measures the strength of heat seals formed between thermoplastic surfaces of flexible webs, immediately after the seal has been made and before it cools to room temperature. This heat seal property is important since this situation occurs on vertical form-fill-seal packaging.

In the heat sealing process, contents are dropped into the bag immediately after the horizontal seal bars have opened. Since the content can be heavy, the hot seal must be able to withstand high loads, thus requiring a high hot tack force. This measurement will be of influence while upgrading packaging materials or packing production processes. Seal initiation temperature is defined as the heat sealing jaw temperature at which a specific level of seal strength is obtained and may be determined by plotting the seal strength versus seal jaw temperature.

Strain Gauge Tensile Testing
One of our most essential data acquisition tools is the strain gage. Forces or loads are related to the stress in an object. Since stresses cannot be measured directly, it is easier to measure strains, the small amounts of stretching that occur in all materials when they are under load. With information about strain, the relationship between stress and strain can be used to determine the forces in an object. The most common reasons to apply strain gages include assessing the root causes of failures before products go to market.
