The main function of composite flexible packaging
Our products are flexible plastic packaging with multi-layer lamination method. The main functions of the composite flexible packaging are:
1. Communication function with users
Through different printing methods, useful information is delivered to consumers, such as the name of the content, ingredients, shelf life, usage, etc., and exquisite printing is used to attract consumers' attention and induce the desire to buy.
2. The function of protecting the contents
Various materials with different properties, such as film materials with different functions such as printability / barrier function / heat sealability, are combined through different laminating methods. Among them, materials with barrier function, such as aluminum foil / various coatings / co-extrusion film of high molecular polymer with barrier function / coating or adhesive with barrier function, etc., provide the content with: moisture positive barrier / Oxygen barrier / ultraviolet barrier / odor barrier and other protections allow the contents to be protected within the designed shelf life.
3. Realize the function of warehousing and transportation
The structure of laminated film flexible packaging must have a sealing layer (or sealing coating), so that the laminated film flexible packaging can be tightly sealed, so that the contents are isolated from contact with the outside world, and even meet the requirements of inflatable (inflammation gas) packaging, so that The barrier function of the structure of the packaging can play a role in the entire storage and transportation and sales process of the product, including meeting the specification requirements in terms of hygienic conditions.
4. Convenient functions for consumers
Allowing consumers to conveniently use the contents of the package is the last link in the entire product life cycle of composite flexible packaging. Whether it is convenient to use, including being suitable for adults / elderly / children, directly reflects the popularity of the product. For example, is the yogurt lid easy to remove? Can the fragile potato chip packaging be easily torn? Can packaged food be heated directly in a microwave oven? etc.
