The word “compound” in flexible industry actually means “lamination”. That is to bind films of different properties together in a certain way, and sealed, so that to protect the content. The laminated structure of flexible packaging can be divided into many categories according to different combinations, so we cannot use only one system to describe different structures. However, the structures of conventional flexible packaging are often distinguished by its outer layer, middle layer, adhesive layer, inner layer. Typical three - layer composite structure is as shown in picture 1-1.

Gas resistance, also known as gas permeability, according to the definition of the Chinese standard GB*T1038-200- "The gas permeability test method - differential pressure method of plastic film and sheet", gas transmittance refers to the gas volume through unit area of the sample in the unit time under a constant temperature and unit pressure difference. They are expressed as value of volume at standard temperature and pressure with unit of :cm3*m2·d·Pa. For the quality assurance in food circulation, gas resistance mainly refers to the ability to prevent O₂, CO₂ and N₂ through the food packaging during circulation.

The packaging of consumed foods can be divided into convenient food, puffed food, pastries & biscuit, dairy product & baked goods, candy & preserved fruit, meat product, pre-made food, roasted nuts, frozen food,health care, grain & oil, sauce, wine & beverage, tea & instant drink etc.

According to the pouch type, the pre-made pouch commonly includes Stand-up pouch, Stand-up Spout pouch, Stand-up zipper pouch, 3 side seal pouch, Flat bottom zipper pouch(8 side seal), Pillow pouch, BIB(Bag in Box), shape spout pouch etc. If classified by application, it mainly includes dry food pouch, vacuum pouch, liquid pouch and retort pouch etc. 

Due to the diversity of food, the complexity of ingredients, and the variability of food quality caused by the circulation environment, the application of Food packaging materials and technology has become very complex.

Undoubtedly, 2023 will be a year full of challenges and variables. Under this era, "internal competition" has become a key word. In the face of fierce competition and changing market, it is particularly important for enterprises to deal with the difficulties and look for breakthroughs. Recently, LD PACK received an invited interview from the editorial department of PACKAGING FOREFRONT. Now, let's see how LD Pack broke through the dilemma and reversed the trend, and what is the forecast and outlook for the market prospect in 2024.
