Specialty Products

In addition to our offering of commodity resin materials, Impact Plastics offers a unique portfolio of specialty products.  Learn more about our specialty products below!


UltraClear Polypropylene

impact-plastics-hazy-pp-vs-ultraclear-pp-comparisonA highly efficient and aesthetically pleasing commercial packaging material with a transparency and clarity comparable to PET and PS, UltraClear polypropylene is setting a new standard for clarity in polypropylene plastic.  With UltraClear PP, the natural “milky” or “hazy” appearance typical of polypropylene plastic, is replaced by a beautiful clear material material with a glass like transparency, even in thicker parts.

With UltraClear PP, consumers can experience the same level of clarity and aesthetics found in other clear polymers such as PET / PET-G, OPS, PVC and PLA, while taking advantage of the cost efficiency, functional properties and sustainable attributes associates with polypropylene.

In addition to the improved clarity and aesthetics, UltraClear polypropylene also presents a number of advantages such as:

  • Low densityImpact-Plastics-Specialty-Products-UltraClear-PP
  • Lightweight
  • Cost efficiency
  • Lower carbon footprint and greater energy savings
  • Microwavable
  • Compatible with hot-fill processes
  • High impact resistance
  • Strong and flexible parts

Mineral Filled Polypropylene Sheet

Working with polypropylene sheet for the first time often presents new challenges for thermoformers including shrinkage, low rigidity, and low stiffness. The addition talc or calcium carbonate mineral fillers can help remedy these problems while contributing added benefits compared to resin-only formulations.

Calcium Carbonate (CaCO3) Filled Polypropylene Sheet

CaCO3 is one of the most widely used mineral fillers in the plastics industry, and its use in rigid packaging has increased significantly over the years.  The addition of calcium carbonate to polypropylene sheet has been shown to improve the performance of several properties including improvements to:

  • Heat deflection temperature
  • Increased impact strength
  • Stiffness
  • Barrier properties
  • Print quality

Additional benefits of using CaCO3 mineral filler in polypropylene sheet include:

  • Streamlined processing – CaCO3 allows the plastic to heat & cool faster, resulting in improved productivity, higher output and faster conversion rates.
  • Reduced shrinkage – improved heat deflection allows the plastic to cool down faster during thermoforming, helping to reduce shrinkage and warping.
  • Cost reduction – CaCO3 allows for the replacement of up to 40% of the plastic, displacing resin and resulting in raw material cost savings.
  • Improved sustainability – Use of a CaCO3 filled product results in displaced petrochemicals and energy savings as a result of increased productivity.
  • FDA approved – CaCO3 additives used by Impact Plastics are FDA approved for food contact applications.

Talc Filled Polypropylene Sheet

Similarly to CaCO3 filler, the use of Talc in polypropylene sheet helps to remedy several common challenges of thermoforming polypropylene while enhancing several properties of the polymer.  The use of talc in polypropylene sheet has been shown to improve the performance of several properties including improvements to:

  • Increased rigidity
  • Resistance to heat
  • Increased heat deflection
  • Faster cooling
  • Reduced Shrinkage

Unlike calcium carbonate, however, the addition of talc results in a significant decrease in impact strength, so if high impact strength is an important specification, CaCO3 is the better choice.

Specialty and custom formulations of CaCO3 and Talc filled polypropylene are available upon request to achieve particular property specifications.


Oxygen & Moisture Barrier Grade Polypropylene Sheet

When working in the food packaging industry, oxygen and moisture barrier properties are critical specifications.

When it comes to moisture, PP possesses inherent moisture barrier properties. PP has a Moisture Vapor Transmission Rate (MVTR) of 0.5 (g-mil.100 in. 2/24hr.). The MVTR is a measure of the passage of gaseous H2O through a barrier – the lower the rate, the longer the package protects its contents from moisture and ensures that moisture of the product remains the same.  This means, not only does the material keep unwanted moisture out, but it keeps moisture in, making it an ideal for food certain packaging applications, such as bakery applications, where it is important for the food to retain it’s moisture content. As a basis of comparison, other common food packaging materials such as PS and PET, have a MVTR of 10.0 and 2.0, respectively.

When it comes to oxygen barrier properties, PP is not traditionally seen as an effective oxygen barrier, however Impact Plastics has recently developed a proprietary formulation with superior oxygen and moisture barrier properties.
