Processes
Spartech utilizes three processes for manufacturing packaging rollstock and thermoformed containers.
 |
Multi-Layer
With the ability to extrude up to 9 layers, multi-layer sheet is ideal for many of the most demanding food and medical packaging applications. |
| |
|
 |
Lamination
Laminated sheet is a cost effective way to create "value added" performance with minimal to no changes necessary to the thermoforming process or tooling. |
| |
|
 |
Mono-Layer
Low cost material options for low and non-barrier applications.
|
Features & Benefits
|
| Multi-Layer |
| Multi-Layer Co-extrusion |
Multi-layer structural integrity with capped barrier materials - up to 9 layers; Superior Organoleptics |
| High Barrier |
Strong oxygen & moisture vapor transmission protection for product-sensitive and long-term shelf life applications |
| Customized Performance |
Symmetrical & asymmetrical multiple material structure configurations |
| Regrind Utilization |
Extruded into sheet structure and capped, providing material cost reduction |
| Applications |
Aseptic, Hot Fill, M.A.P, C.A.P, Retort, Cold Pack |
| Lamination |
| Mono-Layer with Lamination |
Multiple base materials combined with multiple lamination structures for customized "value-added" performance |
| Medium to Low Barrier |
Provides barrier lamination opportunities to existing "mono-layer" applications with minimal process change and no tooling modifications. |
| Performance |
Customize seal & peel characteristics to traditionally hard-to-seal materials |
| Clarity |
Minimal effect on clarity with the value-added benefit of medium to low barrier performance |
| Applications |
M.A.P, C.A.P, Ambient, Dry Fill, Cold Pack |
| Mono-Layer |
| Single Layer Structure |
Application performance-specific |
| Cost |
Lower cost material option vs. multi-layer or lamination for low or non-barrier applications |
| Applications |
Ambient, Dry Fill, Cold Pack |
 |
|
Spartech's 7 packaging sheet facilities are equipped with extruders capable of manufacturing products ranging from multi-layer, laminated, and mono-layer sheet and rollstock. |
