Used materials:

One layer films - APET, CPET, PVC, PS, OPS, HIPS, PP, EPP (microporous PP)  - with thickness of the film from 0,2mm to 2.4mm.

Multilayer barrier films - АPET/PE, APET/EVOH/PE, PS/PE, PS/EVOH/PE, PS/PETG, PP/PE, EPP/EVOH/PE, PP/EVOH/PP, PP/EVOH/PE, APET/PETBlend/APET, PETBlend/PE, EPETBlend/PE, PETBlend/EVOH/PE, EPETBlend/EVOH/PE, PVC/PE, PVC/EVOH/PE - with thickness of the film from 2mm. Usually one of the middles layers is EVOH – the polymer with the lowest permeability of gasses – 1-2 sm3/m2 24h bar of a film with thickness of 25µm. PET also shows good results in the permeability of gasses – 45-90 sm3/m2 24h bar with the same thickness of the film - 25µm.

Antifog and antistatic additives are also used.

Nanocomposite materials – the new materials in the packaging - These are polymer structures with added particles with size in the nanometer range (nanofillers). The concentration of the nano particles in the material is less than 5%. The main polymer could be PP, PET, PE, Nylon etc. The result is high temperature resistivity , barrier qualities, sturdiness, low weight, ability to "signalize" presence of food pathogens by changing the color or fluorescenting, antibacterial and antioxidant properties (active packaging) etc. In the creation of nanocomposite materials at various properties and applications in the packaging industry run by large companies such as Kraft, Kellogg's, Honeywell, Bayer, Ube America, Mitsubishi Gas Chemical.
The trend is nanocomposite material to displace some traditional barrier materials due to its good performance and lower cost.

Application of nanomaterials

PVC, APET, RPET – packages for household products, blisters, inserts and die boxes. These are polymers with high transparency and gloss

PP –packaging of food products with high fat content - margarine, cream, ice cream, strained milk of mayonnaise-based salads, ready meals, fish and meat products and desserts. Polypropylene with appropriate additives acquired resistance to low or high temperatures. This allows its use for:

  • freezing of food
  • heating in a microwave or conventional oven
  • UV sterilization
  • thermal treating in autoclaves and pasteurizers with counter pressure

EPP –foamed polypropylene microporous structure have excellent barrier properties, strength and relatively light. Boxes of this material are opaque and have an excellent presentation.

PS, OPS, HIPS –dairy products with low fat pads sweets and biscuits.

АPET– boxes with high transparency, brilliance and strength - for salads, fish, pastries, ice creams, etc.., beer mugs.

Multilayer films and nanocomposite
The purpose of the packags from multilayer films and nanocomposite materials is for packaging food products in vacuum or modified gas environments, as well as for active packaging - MAP (Modified Atmosphere Packaging), CAP (Controlled Atmosphere Packaging). Durability of the product is increased many times without adding of conservants, while maintaining the taste, natural color and odor. It is suitable for salads prepared, dishes, desserts, vegetables, fruits, meat products, fish, legumes.
