Polyamide Cast Fims

Description and Features

Polyamide films are used for lamination with other polyethylene or polypropylene films, to complement the good water vapor barrier of these films with the gas barrier properties of polyamide.

The usual laminate systems (two, three and up to five layers) are as follows: PE/PA, PE/PA/PE, PE/PA/EVOH/PA/PA/PE.

Once laminated, they are used for packaging and preservation of food, pharmaceutical, and medical products.

R&R offers it in different thicknesses and with different thermoformable properties.

APPLICATIONS:

INDUSTRIES:

They are used for the manufacture of bags, lids, and bases, responding to the requirements and expectations of each industry:

Food: Oxygen sensitive products such as meat, sausages, cheese, coffee, stand-up bags for sauces, processed food, etc.
Pharmacy: products susceptible to sterilization, single-use medical products (surgical material, gauze, syringes)
Sharp products: screws, etc.

PACKAGING PROCESSES: thermoforming, flow pack, vacuum bag.

THERMAL PROCESSES: pasteurization, sterilization, microwave use, among others.

FINISHING:

PROPERTIES:

Medium barrier to oxygen, nitrogen, carbon dioxide, chemicals, and aromas.
Excellent optical properties of brightness and transparency.
High flexibility and thermoformable.
High puncture resistance, e.g., packaging of products with sharp edges to avoid punctures and vacuum loss.
Chemical resistance to fats, oils, solvents, and acidic foods.
Good mechanical properties such as strength, stiffness, and toughness.
High melting point: Capable of receiving different sterilization treatments. Can be used in conventional ovens and microwave ovens.
Excellent machinability.
Perfect winding.
Uniform thickness distribution.
Surface with corona treatment, for laminating and printing.
Food suitability.
Used for laminating with other materials such as CPP, PE, EVOH, BOPP, BOPA, PET, etc.
