Les pièges de l'emballage : les 3 principaux points à surveiller pour les bouteilles en PE, PET et PP avec Scott Roman
PET, PE, and PP bottles are among the most widely used plastic packaging options in beauty and personal care, appreciated for their durability, flexibility, lightweight convenience, and cost effectiveness. However, these materials can present challenges to brand owners and packaging engineers such as overflow capacity, decoration integrity, and material compatibility. Below, I outline the top three pitfalls associated with PET, PE, and PP bottles, the potential impact on your brand, and best practices to avoid them.

1. Capacité de débordement insuffisante (OFC)
Commonly overlooked overflow capacity is crucial as an undersized bottle can significantly disrupt your product labeling, causing regulatory issues and consumer disappointment.
Implications
- Misleading label claims may lead to regulatory penalties.
- Consumer dissatisfaction due to perceived underfilling of the product.
How to Avoid: Start with the OFC indicated on your bottle’s technical drawing, then deduct:
- Plastic bottle tolerance
- Volume displacement from internal components (e.g., pump, dropper, wiper, rod & applicator, orifice reducer plug)
- Required headspace
- Tolérance de l'équipement de remplissage
The resulting volume after these deductions gives your accurate legal label claim in milliliters or fluid ounces. If claiming by weight, convert this calculated volume into grams or ounces using your product’s specific gravity.
2. Échecs d'adhérence ou de compatibilité de la décoration
Decoration is a critical piece of brand differentiation, but poor adhesion or compatibility issues can rapidly degrade the visual quality of your finished PET, PE, or PP bottles.
Implications
- Adhesion failures lead to decoration peeling or wearing off without direct product contact.
- Compatibility failures occur when chemical interactions between the product and decoration materials degrade appearance and functionality.
How to Avoid: Ensure rigorous testing of decorated components, including spray coatings, hot-stamping, silk-screening, heat-transfer labels, and pad-printing, for both adhesion and chemical compatibility with your product. Adjustments may involve modifying curing properties, dwell times, inks or lacquers' chemical compositions, selecting alternative foils, or adding a UV-cured clear topcoat to isolate and protect the decoration from the formula.
3. Incompatibilité matérielle avec le produit
Choosing incompatible materials can result in significant issues like product migration through bottle walls or surface deformation known as “paneling.”
Implications
- Product leakage, weight loss, or compromised formulation stability due to ingredient migration.
- Bottle deformation or collapse, causing aesthetic and functional failure.
How to Avoid: Conduct a material science analysis to predict potential interactions between your product's formula ingredients and the bottle’s resin. Identify materials resistant to migration and paneling issues. Always confirm findings through comprehensive package compatibility testing to ensure bottle integrity throughout your product's intended shelf life.
By proactively considering and addressing overflow capacity, decoration integrity, and material compatibility, you will be well on your way to safeguard the quality and reliability of your products packaged in PET, PE, and PP bottles
