  • The surface of the film packaging is soft and smooth, the color printing is beautiful and more diverse than other types of packaging on the market today.
  • Laminated film packaging has the ability to prevent unwanted chemical reactions that lead to damage to goods and food inside.
  • Laminated film packaging is widely used to contain the following goods: Frozen goods, pesticides, cosmetics, instant foods, etc
Advantages and disadvantages of soft film packaging materials
Currently, laminated film packaging is made from many different types of materials such as: PET, PA, MPET, MCPP, CPP, OPP, LLDPE...

MCPP soft film packaging material
MCPP, also known as Metallize CPP film, is a CPP film plated with an additional layer of aluminum on top.
About advantages: MCPP membrane is plated with a thin metal layer, tightly bonded above the membrane surface. Thanks to that, the waterproofing ability of MCPP is often higher than that of regular CPP membranes. In addition, the MCPP membrane is 20 times more waterproof and moisture-proof than the CPP membrane. Besides, MCPP film also has an extremely eye-catching metallic luster, so it is used to print luxurious and classy soft film packaging.
Regarding disadvantages: During the lamination process, MCPP film used with metallic ink will easily peel off. When you shine ultraviolet rays directly on the membrane, it can easily cause the membrane color to change, causing loss of aesthetic value. In particular, ink is often difficult to print on the film-coated surface.

CPP soft film packaging material
CPP film is made from PP plastic granules using non-directional lamination technology. This type of membrane is designed with molecular circuits oriented to stretch and arranged in random order in the molecular structure.
About advantages: CPP membrane has the ability to effectively block water vapor. Low temperature soldering ability, melting temperature ranges from 125 to 140 degrees Celsius. The average thickness of a single film ranges from 20 to 40 mic, while the composite film ranges from 40 to more than 120 mic, depending on needs. Product compartment inside. High film hardness, used as a solder paste layer, depending on requirements, there will be different thicknesses.
Regarding disadvantages: CPP membrane material has poor ability to block N2, O2 and CO2 gases.

OPP soft film packaging material
OPP is a type of film produced from stretchable PP plastic beads. This product is used to produce soft film packaging for herbs, medical supplies, drugs, fertilizer packaging, convenient food packaging, etc.
About advantages: OPP film has high gloss and transparency and is cheaper than other printed films, while also being effective against scratches. OPP film has high durability and sturdiness with good mechanical properties. The waterproof and moisture resistance of OPP is also very good, so it has high applicability in the market.
Regarding disadvantages: OPP film bags are often more sturdy than other soft film packaging bags today.

PET soft film packaging material
About advantages: PET soft film has good waterproofing and heat resistance up to 2000 degrees Celsius. Diverse designs, glossy surface, easy to print labels and logos. In particular, PET film packaging ensures safety for consumers' health.
Regarding disadvantages: Low resistance to N2, CO2, O2 gas and grease. The packaging is easily damaged when in direct contact with essential oils or detergents.

PA soft film packaging material
Advantages: High impact resistance should be used to package heavy foods such as salt and rice. Able to retain food scent for a long time. Good cold temperature resistance, below -150 degrees Celsius. Can preserve food within 24 hours. Limits the growth of bacteria on food inside the packaging.
Regarding disadvantages: PA soft film packaging is difficult to recycle and is not suitable for storing hot food.

Soft film packaging material AL
About advantages: AL film packaging has the ability to retain the taste of food inside well. Highly resistant to corrosion, water and heat. Ability to effectively block sunlight, suitable for storing food with a long shelf life.
About disadvantages: The only disadvantage of aluminum soft film packaging is its poor ability to repel N2, CO2 and O2 gases.

Application of complex soft film packaging
With the outstanding advantages that laminated film packaging brings, businesses and consumers increasingly favor and widely apply it in the following fields:
Store instant dry foods: such as instant noodles, vermicelli, pho...
Snack packaging: The packaging is resistant to oil, UV light and water. At the same time, it helps block oxygen and preserve scent effectively, so it can be used to store snacks.
For storing powders: Laminated film packaging has high mechanical properties and good printing. In particular, this packaging bag has high barrier properties and good UV protection, so it is commonly used in storing powders.
Tea packaging: Laminated film packaging has an effective barrier feature. Besides, they can also resist O2 gas, mold and odor, so they are chosen by tea businesses for product packaging.
