1. Packaging Design and Materials Tetra Pak: Made primarily from paperboard, with thin layers of plastic and aluminum for barrier protection. Lightweight, rectangular or square design optimized for storage and transport. Sealed using heat and pressure to create an airtight closure. Traditional Bottle Closures: Typically used with plastic (PET) or glass bottles. Closures include screw […]

1. Introduction Blow moulding is a widely used plastic processing technique for producing hollow plastic parts such as bottles, containers, and tanks. With growing environmental concerns and regulatory pressures, the industry is shifting toward sustainable materials. Bio-based and biodegradable polymers offer an eco-friendly alternative to traditional petroleum-based plastics. 2. Definitions Bio-Based Polymers: Derived wholly or

In recent years, sustainability has become a central focus in the cosmetics industry, driving a significant shift in packaging practices. With growing environmental awareness and increasing consumer demand for eco-friendly alternatives, brands are now investing in biodegradable cosmetic packaging moulds—a breakthrough that aligns beauty with sustainability. These innovations are not only reducing the ecological footprint

The COVID-19 pandemic dramatically altered global hygiene practices, catapulting hand sanitizers into essential daily-use items. This sudden surge in demand not only impacted the formulation and production of sanitizers but also brought packaging to the forefront. One packaging innovation that gained particular prominence during this period was the flip-top cap. This case study explores the

Blow moulding is a manufacturing process used to produce hollow plastic components such as bottles, containers, tanks, and drums. As environmental sustainability becomes increasingly important, the recycling and reuse of blow moulded products have emerged as critical strategies for reducing plastic waste and conserving resources. 1. Overview of Blow Moulded Products Blow moulded products are

In the cosmetics industry, ensuring that packaging is compatible with manufacturing moulds is critical for quality, safety, and production efficiency. Mould compatibility testing helps confirm that the packaging components—such as bottles, caps, jars, and dispensers—can be reliably and consistently produced using the intended moulds without compromising product integrity or aesthetics. 1. Purpose of Mould Compatibility

As the global demand for sustainable packaging solutions grows, innovations in closures—caps, lids, seals, and wraps—have become increasingly important. Traditional closures are often made from non-recyclable plastics that contribute to long-term environmental pollution. In response, scientists and companies are now developing edible and biodegradable closures that align with the principles of sustainability and circular economy.

Lightweighting—reducing the material mass of a product without compromising performance—is a key trend in modern manufacturing. In the field of blow moulded products, particularly for packaging and automotive applications, lightweighting has emerged as a critical strategy for cost reduction, sustainability, and regulatory compliance. Drivers of Lightweighting Sustainability Goals Reducing plastic usage aligns with global sustainability

Cosmetic moulding plays a crucial role in the aesthetics and functionality of beauty and personal care products. From compact cases and lipstick tubes to cream jars and pump bottles, these components must not only appeal visually but also maintain their integrity under various environmental conditions. One of the most significant challenges faced in cosmetic packaging

Self-sealing and pressure-responsive closures are innovative mechanisms used in various industries, including pharmaceuticals, food and beverage, automotive, and aerospace. These closures are designed to maintain the integrity of a container by automatically sealing when not in use and responding to internal or external pressure changes without manual intervention. 1. Definition and Functionality Self-Sealing Closures: These
