Plastic Packaging - Which Plastic For What Product?

PLASTIC TYPES DESCRIPTION RAEPAK USES; PET Plastic: Polyethylene terephthalate is commonly abbreviated PET, PETE, or the obsolete PETP or PET-P and is the most common thermoplastic polymer resin of the polyester family and is used in fibres for jars, containers for liquids and foods including PET bottles, thermoforming for manufacturing, and in combination with glass fibre for engineering resins.

PVC vs. PET vs. PP | Which Material should I use for ...

May 02, 2018 · The most common plastic used in this industry is PP. Other times, PET will be used with other acrylic ingredients. PP plastic packaging is used in the cosmetic industry because it is very durable. It can withstand temperatures up to nearly 240° Fahrenheit. So, plastic packaged hair products will not bend to heat from steam or direct contact.

Supeer C6 and C8 mLLDPE resins offer high puncture resistance and toughness, while SABIC HDPE resin portfolio is said to offer high stiffness.

PET polyester plastic - TECAPET | Ensinger

This material has long been referred to as PET-P plastic, but this is an outdated form of reference for PET material today. Due to its good creep strength, low moisture absorption and outstanding dimensional stability, PET plastic material is extremely well suited for applications where complex parts and the highest requirements regarding ...

Polyethylene & Polypropylene in Flexible Barrier …

yPE & PP are used directly or indirectly in flexible barrier packaging. yTo achieve oxygen (gas) barrier, PE & PP are typically coextruded or laminated with other materials. yHDPE MVTR grades provide good moisture barrier properties. yManufacturing methods and process conditions influence barrier properties.

Polypropylene vs. Polyethylene: How Are They Different ...

Jul 26, 2019 · There are a few parameters that are common across all types of PE. Compared to PP, PE is more flexible than rigid, which gives it better ductility and impact strength. It also has good moisture resistance and is a good electric insulator. Limitations. Similar to PP, PE exhibits poor resistance to UV radiation and is highly flammable.

MATERIALS: Performance in Polyethylene: Density Matters ...

Jun 19, 2014 · PE, however, can be manufactured across a range of densities that are related to the spacing between the polymer chains. The original PE that was created in the 1930s by placing ethylene gas under extremely high pressures and temperatures was what today is called low-density PE (LDPE).

Which is better- Polypropylene or Polyethylene?

The density of polypropylene (PP) is between 0.895 and 0.92 g.cm. The density of polyethylene can vary from a low of 0.857 g/cm3 and to a maximum of 0.0975 gm/cm3. As you can see, PP has the lowest density. Polyethylene is further broken down into weights or densities which is done so the plastic can serve a more specific purpose.

What is the best adhesive for polyethylene? How can you ...

Polyethylene is a non-polar polymer, because its chains contain only -CH 2 - groups. For PE bonding is necessary to increase its polarity and/or hydrophilicity.

Which Plastics are Safe for Food Storage and How to Use ...

PET is the easiest plastic to recycle. It is a clear, strong and lightweight plastic that makes it a good option for storing water and food even for the long term. This type of container has good oxygen barrier qualities and can be used with oxygen absorbers to store bulk dry foods.

Polypropylene (PP) Plastic: Types, Properties, Uses ...

The main challenge in PP recycling is related to its amount consumed – currently nearly 1% PP bottles are recycled as compared to 98% recycling rate of PET & HDPE bottles together. The use of PP is considered safe because it does not have any remarkable effect from an occupational health and safety point of view, in terms of chemical toxicity.

Environmental Stress Crack Resistance of Polyethylene

geomembrane materials, but other PE materials have been tested to gauge slow crack growth performance. Typical test conditions are 50°C in a 10% IGEPAL® solution and the applied load is 30% of the sample’s yield stress. The notch depth is 20% of the sample thickness. This method is shown in Figure 2. Time to failure is recorded. Results
