Extrusion coating vs. adhesive lamination: A comparison study Paid Members Public
Both adhesive lamination and extrusion coating can be used to provide a structure for flexible packaging. The question of which method to use often is based on what asset is available, not what system will be best for a given structure. This article will look at the reasons an adhesive
Economic Front: It’s hard to tell where you’re going if you don’t know where you are... Paid Members Public
The US Real Gross Domestic Product declined at a 1.6% annual rate in the fi rst quarter of 2022. Real Gross Domestic Income rose at a 1.8% rate. Over the last six quarters, GDP has grown at a 4.1% rate versus 7.3% for GDI (see line
Curbside-recyclable standup pouch earns top Dow Packaging honor Paid Members Public
Melbourne, Australia-based O F Packaging has earned the 2021 Diamond Award in the annual Dow Packaging Innovation Awards program. The flex-pack converter’s curbside-recyclable, high-barrier standup pouch for Brookfarm’s line of toasted muesli breakfast cereals (see Figure 1) demonstrated excellence in all three judging criteria, according to a panel
Coating Concepts: Product-process integration: What is the right coating method? Part 1 Paid Members Public
There are three common ways to pick a coating method: inertia, flowcharts and screening tables. The practical advantages of inertia speak for themselves. However, the use of removable-cartridge coaters has reduced the barriers to change. Also, it often is more economical to find a contract manufacturer with the “right” method
Web-handling best practices for corona treating on R2R-converting lines: Why the web path matters Paid Members Public
Did you know that poor web handling creates trouble for corona surface-treatment operations? It often is the hidden root cause of suspected treatment issues and can lead to significant downtime. As converters run higher line speeds with thinner films, greater attention is required to guarantee proper web handling. In addition
WEB WISE: What’s behind the real problems caused by air entrainment? Paid Members Public
Air entrainment is real, and it can cause real problems, but only in certain circumstances. When and where and what are the salient questions. Let us begin with the “what” of the mechanics. As seen in Figure 1, air “sticks” to both the web and the roll(er). During run,
VACUUM VERBIAGE: How can polymer marking improve packaging recycling rates? Paid Members Public
In the area of brand authentication, anti-counterfeiting and supply-chain verification, it is common to use overt or covert marking of the product or packaging. The features used for marking include colored fibers; specialist inks, such as infrared, fluorescing, color-shifting, metallic or holographic inks; barcodes; two-dimensional (snowflake) barcodes; and/or embossed
Thermoset film offers soft, high temperature-resistant stretchability for printed electronics: Part 1 Paid Members Public
A primary factor limiting the deployment of printed electronics is a dearth of application-specific substrates. Conventional thermoplastic polymer films like TPU and PET, typically employed for printed electronics, exhibit poor temperature resistance and relatively high hysteresis, creating significant challenges for printing and curing of functional materials, such as conductive pastes,
