Information Density — The Lens
Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.
Info Density
Power-words vs. Substance ratio.

The site provides concrete macro-level figures such as Over 2.0 Billion lbs. Annual Raw Materials and Over 40 Locations, which provide substantial weight to its claims of scale. However, heading fluff is present in tags like H2 EXCELLENCE IN SERVICE, RELIABILITY AND QUALITY, which uses three power words without a specific noun or metric. The body text often retreats into generic descriptors like quality, innovation and expertise and stands apart from the competition without defining the technical basis for these claims. While the location list is highly specific, the product descriptions for Custom Films and Stretch Films lack technical specifications, gauges, or material science details.
Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.
