Barrier Properties
Sachet bags designed with effective barrier layers prevent moisture, oxygen, and light from affecting the product, which is especially crucial for perishable foods, pharmaceuticals, and cosmetics. High-quality materials prolong shelf life and ensure product integrity.
Sustainability and Eco-friendliness
With environmental concerns rising, manufacturers are exploring recyclable, biodegradable, and compostable sachet options. Innovations in eco-friendly materials are changing the landscape of sachet bags, making them more sustainable without compromising function.
Manufacturing Process of Sachet Bags
Material Selection and Preparation
Choosing the right raw materials is the first step. Compatibility with product type, barrier needs, and eco-friendly requirements influence selection. Lamination and printing are then performed to prepare the films, incorporating branding and design elements.
Bag Making Procedures
The process involves cutting, sealing, and folding the films into the desired sachet shape. Advanced machinery automates these steps, ensuring precision and consistency. Integration of printing during production allows for high-quality graphics directly on the packaging surface. Rigorous quality control is essential to detect leaks, seals, or print defects.
Packaging and Shipment
Filled with the designated product using filling machines, sachets are then inspected for quality and integrity. Proper packaging and logistical planning ensure timely delivery, maintaining product safety throughout distribution. Some companies also adopt in-line inspection systems to minimize defects.
