Customised corrosion-resistant, leak-proof, self-standing foil-plastic spray bags, suitable for dete

Packaging bags are made from a variety of materials, the most common of which include:

1. Polyethylene (PE): There are various types, such as high-density, low-density, and linear low-density, which are characterised by high-temperature resistance, low-temperature resistance, acid and alkali resistance, good airtightness, and chemical corrosion resistance. It is suitable for high-temperature environments and is widely used in food packaging, including juice.

2. Polypropylene (PP): It has good breathability, transparency, and processing performance. It is primarily coated on films and other composite materials (such as cellophane and aluminium foil) and used for beverage packaging containers.

3. Polyester (PET): It has good crystallinity, is colourless, odourless, and non-toxic. Food packaging containers made from polyester materials have a high gloss surface similar to glass, making them widely applicable for packaging hot beverages like tea.

4. Nylon: A high-performance synthetic fibre material with excellent abrasion resistance, tear strength, and barrier properties. It is commonly used to manufacture packaging bags for juice beverages with high barrier performance requirements.

5. Aluminium foil: A metallic packaging material with excellent barrier and light-blocking properties, effectively protecting juice beverages from light and oxygen exposure to extend shelf life.

manufacturing process

1. Raw material preparation: Select suitable raw materials for juice packaging, such as food-grade PE, PP, PET, etc.

2. Blown film or cast film: Use blown film or cast film technology to convert raw materials into film.

3. Printing: Print patterns and text on the film to convey brand information and attract consumers.

4. Laminating: Laminate different materials together as needed to enhance the barrier properties and mechanical strength of the packaging bags.

5. Bag Making: Use a bag-making machine to convert the laminated film into packaging bags.

6. Sealing and Cutting: Use a cutting machine to seal and cut the filled juice beverage packaging bags, making them convenient for consumers to use.
