Principle Flexible Packaging Performance Characteristics

For many years, flexible packaging professionals summarized the functions of packages into three major “buckets”: Protection, Utility, and Motivation. Here, we expand on those buckets for flexible packaging and learn how it can perform many functions.

1.Flexible packaging protects for delivery.

A package protects a product—and itself—from the rigors of shipping, distribution, storage, and use. A consumer pays for a product and expects to receive the full value. Flexible packaging plays a crucial role in delivering that value

  • Hermetic seals that completely contain the product, protecting it from spilling or contamination from the environment.
  • Toughness that prevents breaching of package walls by outside physical forces or abuses
  • Customize package sealing response to a wide variety of package machine sealing methods and conditions, permitting fast, dependable production of sealed packages.
  • Withstand post-fill processing conditions such as freezing temperatures, high heat, humidity, and radiation sterilization.

2.Flexible packaging protects for processability.

The objective is to minimize waste through the entire chain of production and use of a product. Successful flexible packaging should be able to:

  • Customize the force required to slide the packaging material or the package against other materials.
  • Be optimized for packaging machine ease of operation or to prevent items from sliding relative to each other in distribution.
  • Customize package sealing response to a wide variety of package machine sealing methods and conditions, permitting fast, dependable production of sealed packages.
  • Withstand post-fill processing conditions such as freezing temperatures, high heat, humidity, and radiation sterilization.

3.Utility for consumer containment, freshness, and tailored transmission.

Every product has its own needs for freshness and barrier properties. Flexible packaging can:

  • Provide tamper-evident features that help ensure the product integrity for use—or that it’s even still there.
  • Offer opening and resealing features that facilitate multiple package accesses and uses while securely containing the product.
  • Be able to customize the rate of transmission of gasses through the walls of sealed packages.
  • At the high-barrier end of the spectrum: Provide extremely low rates for long-term storage of sterilized food at room temperatures or medications in humid environments.
  • At the low-barrier end of the spectrum: Provide very high rates for breathable produce packages, with the ability to create customized levels for individual produce items.
  • Allow controlled venting of steam released in microwave heating to cook product while maintaining product moisture and avoiding leakage.

4.Utility for consumer-added functionality.

Flexible packaging technologies have progressed to improve product storage and add preparation functions.

  • Shelf life: Vacuum-packed food or personal items for long-term storage.
  • Microwavability: Food that can be warmed or heated thoroughly in the package.
  • In-package microwave “cooking”: Packages that can “cook” a product in microwave ovens include those for popcorn, brown-and-crisp sandwiches, and freshly made pasta dishes.
  • Ovenability: Retail packages that cook roasts, bake whole turkeys ,etc. in conventional ovens.

5.Motivation at retail.

Packages help motivate purchase decisions by presenting the product and its desirable attributes to consumers in a way that the product both stands out from the rest and engenders trust in its quality. The appearance and style of flexible packaging connect the consumer’s needs and expectations to the product, and the package can truly become the product. Flexible packaging should be able to:

  • Provide a smooth surface for high-quality printed images, including the ability to bury the print beneath the outside package layer for extra gloss and sparkle and for resistance to abrasion.
  • Easily incorporate pigmentation to provide uniformly colored packages that protect products against damaging light frequencies.
  • Offer options for a variety of label shapes, including whole-body labels that shrink to conform to complex primary package shapes.

6.Motivation for repeat purchase.

Packaging should reinforce the positive purchase retail decision in subsequent moments of truth. First, the value of the package should reflect the value of the product. In addition, flexible packaging can:

  • Add functionality for more comfortable or efficient in-home use.
  • Bring new use occasions to the user to expand or encourage consumption.
  • Solve an in-home use problem with easier storage, refill, or disposal experiences.
  • Surprise the consumer with an added-value feature.
