CPP
Description: Cast polypropylene (CPP) is extruded in-house, and can be used for a variety of applications, including, twist film, flow wraps, bag film, and a myriad of special applications. CPP extrusion is very common in Europe and Asia, but is more of a specialty film in North America.
Typical Features: Excellent clarity, gloss, scratch resistance, heat seals, and hot tack. Good stiffness.
Barrier Properties: Excellent water barrier, poor gas barrier.
Typical Grades: Ranges from 60 ga up to 4 mil.
Applications: CPP is an excellent alternative to PE for bags with less than 1 lbs of content. CPP has significantly better heat seals than OPP and easily seals through contamination for dusty products. CPP is an excellent sealant web, laminated to OPP, PET, Paper. It is also often used for Twist Wrap applications.
OPP
Description: Oriented polypropylene (OPP or BOPP) is a commodity film that is typically produced in dedicated factories in North America, Asia, or the Middle East.
Typical Features: Excellent clarity, gloss, and stiffness. Good heat seals.
Barrier Properties: Excellent water barrier, poor gas barrier.
Typical Grades: We generally stock 70ga, 80 ga, 1 mil, 1.2 mil, and 1.4 mil.
Applications: Sealant web or outer web in laminations, or a stand-alone film for certain applications. Most grades of OPP is sealable on 2 sides, and can in most cases be fin sealed or lap sealed.
PE
Description: Polyethylene is extruded throughout North America, and is a readily available and commonly used material. We extrude PE in-house and also buy certain grades from local suppliers, depending on the requirements. PE is typically blown, but can also be cast. Cast PE is typically softer and clearer than blown PE.
Typical Features: Excellent heat seals, puncture resistance, and impact resistance.
Barrier Properties: Good water barrier, poor gas barrier.
Typical Grades: 1.5 mil, 2-4 mil.
Applications: PE is most commonly used as the sealant web in laminates of all kinds
PET
Description: Polyester (PET) is a commodity film that is typically produced in dedicated factories in North America, Asia, or the Middle East.
Typical Features: Excellent stiffness, clarity, gloss and heat resistance.
Barrier Properties: Excellent gas barrier, poor water barrier.
Typical Grades: We stock 48 ga PET, which is the most common grade in North America for flexible packaging.
Applications: Polyester is almost always used as an outer web in laminations. The heat-resistance of PET makes it ideal for this application, creating a very "forgiving" material that is easy to run. Heatsealable grades of PET do exist, but they are not that common. As a result, PET laminations require a fin seal.

Metallized OPP
Description: Metallized OPP is another common barrier material. We metallize our OPP in-house by evaporating a thin coat of aluminum onto the film under vacuum.
Typical Features: Similar to OPP
Barrier Properties: Outstanding gas barrier and water barrier.
Typical Grades: 70 ga PET is stocked and metallized for the application. Other grades are also readily available, but since the metal provides the barrier, 70 ga typically works for a multitude of applications.
Applications: Metallized OPP is often used as the sealant web in an OPP/MET OPP lamination for a variety of applications from flow wraps for chocolate to VFFS for candy, etc. Metallized OPP can also be surface printed and used as a single web
