Rigid Packaging Engineering Support

Solve Rigid Packaging Performance Problems With Engineering Support

Empire EMCO helps manufacturers evaluate rigid packaging problems involving bottle design, closure compatibility, seal integrity, materials, tooling, paneling, stress cracking, structural performance, and other technical packaging challenges.

Packaging Problem Solving

When the Package Is Not Performing, Start With the Cause

A leaking bottle, collapsed sidewall, cracked container, loose closure, or failed seal may look like a simple packaging problem, but the root cause can involve multiple components.

Bottle geometry, resin selection, wall thickness, neck finish, closure design, liner choice, torque, product chemistry, filling conditions, storage environment, and shipping conditions can all affect package performance.

Empire EMCO helps manufacturers evaluate the complete package to identify the likely cause of the problem and determine whether the best solution involves design, material, tooling, closure, manufacturing, or sourcing changes.

Packaging Engineering Capabilities

What Packaging Engineering Challenges Can We Help Evaluate?

Rigid packaging performance depends on how the container, closure, material, product, manufacturing process, and distribution environment work together.

1

Bottle & Container Design

Evaluate package geometry, wall distribution, structural features, handling requirements, label areas, and overall package design.

2

Closure Compatibility

Evaluate neck finishes, closure dimensions, thread engagement, liner requirements, torque, seal systems, and component fit.

3

Seal Integrity

Investigate leaking, sealing failures, liner performance, induction sealing, closure application, and package integrity.

4

Material Selection

Evaluate HDPE, PET, PP, and other rigid packaging materials based on product compatibility, performance, barrier needs, and application.

5

Bottle Paneling

Evaluate sidewall distortion, vacuum formation, product interaction, oxygen loss, temperature effects, and structural design.

6

Stress Cracking

Investigate environmental stress cracking, resin selection, chemical compatibility, geometry, stress concentration, and processing.

7

Top-Load & Structural Performance

Evaluate how containers perform during stacking, filling, palletizing, warehousing, transportation, and distribution.

8

Tooling & Mold Design

Evaluate stock molds, custom tooling, family molds, cavity configuration, design changes, and manufacturability.

9

Prototype & Package Validation

Support evaluation of new package concepts before full-scale production or supplier transition.

Common Packaging Failures

When Should You Request a Packaging Engineering Review?

Engineering support can be useful when a package fails unexpectedly, when a new product is introduced, when suppliers or materials change, or when an existing package needs to be improved.

Our bottle is paneling or collapsing. Evaluate vacuum formation, oxygen loss, bottle geometry, wall thickness, material, headspace, and product interaction.
Our package is leaking. Review neck finish, closure fit, liner, torque, seal geometry, component tolerances, filling conditions, and product compatibility.
Our bottles are cracking. Evaluate resin, chemical exposure, stress points, molding conditions, package geometry, and environmental stress cracking.
Our closure is not sealing correctly. Review thread engagement, neck finish dimensions, cap design, liner choice, application torque, and sealing method.
Our package fails during shipping. Evaluate top load, sidewall strength, case pack, palletization, compression, transportation conditions, and package geometry.
We changed suppliers and now performance is different. Compare dimensional tolerances, resin, manufacturing process, mold design, wall distribution, closure fit, and package specifications.
Evaluate the Entire Package

The Bottle Is Only One Part of the Packaging System

Packaging performance is rarely determined by one component alone. A bottle and closure that work correctly in one application may not perform the same way with a different product, filling temperature, storage condition, or distribution environment.

An engineering review may consider:
Bottle geometry
Wall thickness
Resin and material
Neck finish
Closure design
Liner or seal system
Application torque
Product chemistry
Filling temperature
Headspace
Storage conditions
Distribution environment
Empire EMCO's Approach

How We Approach Packaging Engineering Problems

The goal is not to change packaging unnecessarily. We start with the failure, examine the variables that may be contributing to it, and identify practical solutions that fit the application and supply program.

1 Define the Failure
2 Review Package Components
3 Evaluate Application Conditions
4 Identify Root Causes
5 Develop Solutions
6 Validate & Implement

A Packaging Problem Does Not Always Require a Complete Redesign

In some cases, a small engineering adjustment can improve performance without replacing the entire packaging system.

Optimize the Closure System

Changes to closure design, liner selection, sealing method, neck finish, or torque may improve seal integrity without requiring a completely new bottle.

Modify Bottle Geometry

Structural ribs, wall distribution, geometry, panel design, or other changes may improve package strength and resistance to deformation.

Evaluate Material & Resin

A different material, resin grade, barrier structure, or processing approach may improve compatibility or package performance.

Engineering & Cost

Better Packaging Performance Can Also Reduce Total Cost

Packaging engineering is not only about fixing failures. It can also help identify unnecessary material, over-engineering, excess tooling, production inefficiencies, and avoidable scrap.

A successful engineering review may help improve structural performance while reducing weight, simplifying components, improving manufacturing efficiency, or making alternate suppliers possible.

This is why packaging engineering and cost reduction are often closely connected.

Packaging Engineering FAQ

Frequently Asked Questions About Rigid Packaging Engineering

What does rigid packaging engineering support include?
Rigid packaging engineering support may include evaluation of bottle and container design, materials, wall thickness, closure compatibility, seal integrity, neck finishes, tooling, paneling, stress cracking, structural performance, prototypes, and package failure troubleshooting.
What causes bottle paneling?
Bottle paneling occurs when the sidewalls of a rigid container deform inward. Potential causes may include internal vacuum, oxygen loss, product interaction, temperature changes, insufficient structural strength, wall distribution, or package design.
Why does a bottle leak even when the cap is tight?
A tight closure does not always mean the package has a reliable seal. Leaks may involve neck finish dimensions, closure geometry, thread engagement, liner selection, sealing surfaces, torque, component tolerances, or product compatibility.
What causes plastic bottles to stress crack?
Stress cracking can result from a combination of mechanical stress, material selection, chemical exposure, package geometry, molding conditions, and environmental conditions. The specific cause depends on the bottle, product, material, and application.
Can a closure be changed without redesigning the bottle?
In some cases, yes. If the neck finish and dimensional requirements are compatible, a different closure, liner, sealing system, or torque specification may improve package performance without requiring a complete bottle redesign.
Can Empire EMCO help troubleshoot an existing package?
Yes. Empire EMCO can help evaluate existing rigid packaging systems and identify potential issues involving bottles, containers, closures, materials, seal systems, tooling, manufacturing, compatibility, and supply.
