In vacuum packaging for fresh meat, poultry, and seafood, EVA shrink film has become the preferred solution for an increasing number of food processors. Its ability to shrink tightly around the product after heating is well known, but its greate...

In day-to-day vacuum packaging operations, manufacturers often encounter a puzzling situation: the same vacuum machine, the same product, but different embossed vacuum bags produce noticeably different vacuum times. Some bags reach the desired v...

When designing flexible packaging structures, one of the most critical decisions is which material to use for the heat sealing layer. Polyethylene (PE) and polypropylene (PP) are the two most widely used sealant materials. Combined with polyamid...

In vacuum packaging production, seal leakage is one of the most common and frustrating quality issues. Even when the vacuum level is adequate and the seal appears smooth and intact, packages may begin to leak slowly—or even split open&mdas...

In the procurement of vacuum packaging films, focusing only on price is one of the most common mistakes made by many companies. A price difference of just a few cents per unit may seem insignificant at first. However, once the film is runnin...

In flexible packaging applications across the food, pharmaceutical, and daily chemical industries, package breakage remains one of the most common and costly quality issues for manufacturers. Products such as bone-in meat, frozen seafood wit...

In many cases, films with identical thickness may differ several times in load-bearing capacity. The answer lies in a key mechanical property—tensile strength. And the variation in tensile strength is determined by a combination of materia...

In flexible packaging printing, ink delamination (ink peeling or ink drop-off) is a long-standing and persistent quality issue. Printed packaging may show ink flaking, fading graphics, or partial image loss during post-processing, transportation...

With the European Union’s Packaging and Packaging Waste Regulation (PPWR) set to become fully mandatory on August 12, 2026, Europe’s packaging regulatory landscape is undergoing a major structural shift. The regulation is not only re...

In flexible packaging production, heat sealing temperature is a critical factor that directly affects seal quality. However, its influence on production efficiency, equipment compatibility, and overall yield is often underestimated. Co-extruded ...
