Sustainability Fundamentals

What Is Sustainability in Packaging?

Packaging sustainability is the practice of evaluating environmental impact alongside the performance, cost, availability, manufacturability, regulatory and supply-chain requirements of a package.

Quick Answer Sustainability in packaging means considering how packaging materials, manufacturing, transportation, use and end-of-life affect resources, waste and environmental impact while still ensuring the package protects the product, performs reliably, can be manufactured consistently and supports the needs of the business.

There is rarely one packaging material or format that is universally “most sustainable.” The right decision depends on the product, application, supply chain, sustainability objective and tradeoffs involved.

The Fundamental Concept

What Does Sustainability Mean for Packaging?

Sustainable packaging decisions look beyond a single material, environmental attribute or marketing claim.

Manufacturers may evaluate how much material a package uses, whether recycled content can be incorporated, how the package performs, how it is manufactured and transported, whether it can be recovered after use, and whether the packaging strategy supports regulatory, customer or corporate sustainability objectives.

The packaging still has to do its primary job. It must contain and protect the product, work through the filling and distribution process, meet applicable requirements and be available at the quantity and consistency the manufacturer needs.

Environmental Consideration What materials, resources, energy, transportation and end-of-life factors are associated with the package?
Packaging Performance Will the package protect the product and perform through filling, storage, transportation and use?
Business Reality Can the package be manufactured, sourced and supplied consistently at a workable cost?

Why It Matters

Why Does Packaging Sustainability Matter to Manufacturers?

Sustainability increasingly affects decisions across procurement, packaging engineering, operations, supply chain, compliance, product development and corporate sustainability teams.

1

Regulatory Requirements

Packaging regulations, recycled-content requirements, EPR programs and environmental-claim requirements can influence package design, material selection and documentation.

2

Customer Expectations

Retailers, corporate customers and end users may request recycled content, packaging reduction, recyclability or other sustainability improvements.

3

Corporate Goals

Manufacturers may establish internal goals involving recycled materials, waste reduction, greenhouse-gas emissions or packaging optimization.

4

Material & Supply Decisions

Sustainability goals can change resin requirements, supplier options, lead times, availability and sourcing strategy.

5

Packaging Performance

Changing material, recycled-content level, package weight or design can affect strength, appearance, compatibility, filling and distribution performance.

6

Claim Credibility

Sustainability claims should accurately reflect the package, supporting documentation and applicable requirements rather than relying on vague environmental language.

Sustainability Simplified™ Decision Framework

Sustainability Should Not Be Evaluated in Isolation

A package may perform well against one sustainability objective while creating a challenge somewhere else. Manufacturers should evaluate the complete packaging system and understand the tradeoffs before converting.

What It Means for Your Packaging

How Can Sustainability Change a Packaging Decision?

Sustainability goals can influence nearly every part of a rigid packaging specification—from resin and package weight to supplier selection and end-of-life strategy.

Material Selection

Manufacturers may evaluate PET, HDPE, PP, glass or other materials based on product requirements, performance, availability and sustainability objectives.

Recycled Content

PCR content can reduce reliance on virgin resin but may introduce considerations involving color, consistency, performance, regulatory suitability, cost and availability.

Lightweighting

Reducing package weight can reduce material use, but the package still needs enough strength and durability for filling, stacking, transportation and use.

Design for Recycling

Package components, materials, labels, closures, color and product contamination can influence how effectively a package fits into existing recycling systems.

Transportation & Distribution

Package weight, cube efficiency, supplier location and distribution strategy can influence transportation requirements.

Supply Continuity

A sustainable packaging strategy must also consider whether the required material and package can be sourced consistently at the needed quality and volume.

Before You Make a Change

What Should Procurement and Packaging Teams Evaluate?

Different functions will look at sustainability through different lenses. The strongest packaging decisions bring those requirements together.

Procurement & Supply Chain

✓
Material and component availability
✓
Lead times and supplier capacity
✓
Minimum order quantities
✓
Total packaging cost
✓
Supplier reliability and backup options
✓
Required sustainability documentation

Packaging Engineering & Operations

✓
Product compatibility
✓
Drop, top-load and physical performance
✓
Filling-line performance
✓
Closure fit and function
✓
Appearance and decoration
✓
Distribution, warehousing and shelf-life requirements

Common Misconceptions

What Does Sustainable Packaging Not Automatically Mean?

“Recyclable means recycled.” It does not. Recyclable describes what may happen to a package after use. Recycled content describes material already used to manufacture the new package.
“More PCR is always better.” Higher recycled-content levels can support certain sustainability objectives, but suitability depends on the product, resin, performance, appearance, availability and regulatory requirements.
“The lightest package is always the most sustainable.” Reducing material can be beneficial, but excessive lightweighting can compromise package performance and potentially create product loss, leakage or other waste.
“One material is always more sustainable than another.” Packaging decisions depend on the application and the scope of the comparison. Material weight, manufacturing, transportation, product protection and end-of-life can all affect the result.

Think Beyond the Package Material

Why Does the Full Packaging Life Cycle Matter?

A sustainability decision should consider more than the material visible in the finished package.

The environmental impact associated with packaging can occur during raw-material production, package manufacturing, transportation, filling, distribution, use and end-of-life.

This is why Life Cycle Assessment and life-cycle thinking can be useful when manufacturers compare packaging alternatives. The answer can change depending on the scope, assumptions and data used.

Frequently Asked Questions

Sustainability in Packaging FAQs

What is sustainability in packaging?
Sustainability in packaging means evaluating environmental impact and resource use while also ensuring the package meets performance, cost, availability, manufacturability, regulatory and supply-chain requirements.
What makes packaging sustainable?
There is no single attribute that automatically makes a package sustainable. Manufacturers may evaluate material use, recycled content, recyclability, package weight, transportation, product protection, manufacturing requirements, supply availability and end-of-life as part of the decision.
Is recyclable packaging always sustainable?
Not necessarily. Recyclability is one consideration within a broader packaging sustainability evaluation. The package must also meet the application's performance, manufacturing, supply-chain and other requirements.
Is recycled content the same as recyclability?
No. Recycled content describes material that has already been recovered and incorporated into a new product. Recyclability describes whether the package can potentially be collected, sorted and processed through an appropriate recycling system after use.
Does sustainable packaging always cost more?
No single cost rule applies. Cost can vary based on material, recycled-content level, package design, manufacturing method, quantity, transportation, availability and market conditions. Manufacturers should evaluate total packaging and operational cost.
Can sustainable packaging affect product performance?
Yes. Changing material, recycled-content level, package weight or design may affect physical performance, compatibility, appearance, processing or distribution. Appropriate qualification and testing may be necessary before making a conversion.
What should procurement teams consider when evaluating sustainable packaging?
Procurement teams should consider material and component availability, lead times, supplier reliability, minimum order quantities, total packaging cost, documentation requirements and the ability to maintain consistent supply.
What should packaging engineers consider?
Packaging engineers should evaluate product compatibility, physical performance, filling-line requirements, closure fit, decoration, distribution conditions, storage and other application-specific performance requirements.
How should a manufacturer start improving packaging sustainability?
Start by defining the sustainability objective and the package's non-negotiable performance and business requirements. Then compare packaging options based on environmental considerations, performance, cost, availability, manufacturing, supply-chain risk, regulatory requirements and claim credibility.
