Features & Benefits
- Materials Features
- Advantages
- The outer layer made of polyethylene terephthalate (PET) provides for excellent optical properties (gloss and transparency) and heat resistance of the film.
- The polyamide (РА) layer provides for excellent strength characteristics of the film.
- Ethylene vinyl alcohol (EVOH) procures for a high oxygen barrier and provides for:
- microbiological stability of the products during storage;
- retardation of the oxidation processes that cause rancidification of the fats contained in the food products.
- The inner polyethylene (РЕ) layer allows sealing within a wide temperature range to obtain a tight seal and provides a barrier to water vapor (zero weight losses during storage).
- Biaxial orientation of the film provides for even stretching in the course of molding and excellent strength properties (including the corners).
- The low specific weight of the film (kg/m2) ensures a perfect ratio between the product weight and the packaging weight.
- The combination of different polymer materials in the structure, and the biaxial orientation of the AMISTYLE BP/CP films provide for
- excellent sealability of AMISTYLE BP and AMISTYLE CP between themselves and with other films within a wide range of temperatures
- high strength and puncture resistance, which preserves the integrity of the package at the stages of transportation and storage
- attractive appearance of the packaging material (transparency and gloss), which makes the film virtually invisible on the product
- high barrier to water vapor and gasses (oxygen, nitrogen, carbon dioxide);
The AMISTYLE BP films are produced by an innovative method (triple bubble biaxial orientation) that allows stretching during the thermoforming without critical thinning in certain areas. Thus, the combined AMISTYLE BP and AMISTYLE CP films provide for preservation of food products, prolong their shelf lives, and open the way for packaging of food with the use of high-rate automatic equipment. The thinness of the AMISTYLE BP/CP films contributes to their lower environmental impact due to the reduced amount of polymer wastes. Absence of chlorine-containing substances makes the AMISTYLE BP/CP films more environment-friendly because of their safer disposal of the packaging.

- Application
The AMISTYLE BP films are intended for secondary packaging of various food products (meat-based food, chilled meat, chilled poultry, sausages and delicatessen, chilled fish, cheeses and cheese-based products) by the method of vacuum or MAP thermoforming in order to prolong the shelf life
This Process Operating Manual describes the procedure for packaging of food products by thermoforming with the use of AMISTYLE BP and AMISTYLE СР films. AMISTYLE BP/CP are multilayer heat-shrink vapor- and gastight heat-sealable films made of polyamide, polyolefin, polyethylene terephthalate, EVOH and adhesive (modified polyethylene) permitted by the Russian Ministry of Health for use in the food industry. The quality of the raw materials used for production of the film is confirmed by Russian and international quality certificates. AMISTYLE BP serves as the thermoformable bottom film used to make the tray that contains the food product. AMISTYLE CP serves as the lidding film used to seal the tray containing the food product. The AMISTYLE BP/CP films are manufactured according to Specifications TU 22.21.30-052-27147091-2012 and are intended for secondary packaging of various food products (meat-based food, chilled meat, chilled poultry, sausages and delicatessen, chilled fish, cheeses and cheese-based products) by the method of vacuum or MAP thermoforming in order to prolong the shelf life. The AMISTYLE BP/CP films are suitable for processing on various types of thermoformers. The shelf lives of the food products packaged in the AMISTYLE BP/CP films shall be set by the manufacturers and approved following the procedure stipulated by the laws.
- Printing
The AMISTYLE BP film is suitable for multicolor or CMYK printing.
Printing is applied by the flexographic method. The inks are resistant to boiling, fats, and mechanical action.- Recommendations On Use
- Sealing temperature: 120 – 150 °С
- Molding temperature: 95 – 105 °С

Film storage and transportation
4.1.1. Keep the film in enclosed dry rooms at a distance of not less than 800mm from heaters, in the absence of strong-smelling or corrosive substances, at a temperature from + 5 °С to + 35 °С and relative humidity not more than 80 %.
4.1.2. Transport the film at temperatures not exceeding 40 °С, and protect against direct sunlight.
4.1.3. When the film has been stored at a temperature below 0 °С, keep it at room temperature before processing for at least 24 hours without opening the manufacturer's packing.
4.2. Food product packaging Packaging of food products in the AMISTYLE BP/CP films shall be made in production rooms meeting the requirements of the applicable food safety regulations and standards. To ensure stability of the packaging process, observe the manufacturer-recommended operating modes for the packaging equipment. Loading of the film in the automatic equipment must be made in accordance with the instructions of the equipment manufacturer and the loading procedure. Take care to maintain the film well-tensioned during the operation. The equipment settings (forming and sealing temperature, packages per minute rate, etc.) shall be selected on a case-by-case basis. The AMISTYLE BP/CP films have a heat-sealable polyethylene (PE) layer on the inward side of the film web. Packaging of food products with the use of the AMISTYLE BP/CP films includes the following stages:
4.2.1. Forming of a tray from the roll of the AMISTYLE BP bottom film Trays are made automatically by heating of the rolled AMISTYLE BP bottom film and forming of tray shapes by using of vacuum and/or compressed air flow (depending on the thermoformer design). The maximum depth of a tray formed from the AMISTYLE BP film depends on the number of trays formed per cycle of the equipment; the maximum depth may be as great as 10cm for the 1x1 and 1x2 formats. The maximum depth of the tray formed from AMISTYLE BP depends on the number of trays produced during one operating cycle of the equipment. The maximum tray depth may be as large as 10cm for the 1x1, 1x2 format. The film thickness should be selected based on the packaged product characteristics and the required film stretching depth. E.g., when frankfurters are to be packaged in trays 10-30mm deep, Amistyle BP-60/Amistyle CP-40 films are recommended. Sausage chubs 40-50mm in diameter should be packaged in Amistyle BP-90 or Amistyle BP-110 film in combination with Amistyle CP-50.
Recommended thermoforming parameters for the AMISTYLE BP film:
- Forming temperature: 90-110 ºC
- Film heating time - 2 - 4 s
- Film drawing time 1 - 2 s
- Drawing pressure 1.5 bar - 2 bar
4.2.2. Placement of food in the formed tray
The formed trays are fed by a belt conveyor to the product dosage zone, where the food is placed on the tray automatically or manually. During the dosage take care to match the product volume with the tray size and shape. 4.2.3. Package sealing After dosage of the food into the trays, the thermoformer uses the AMISTYLE CP lidding film to seal the trays with simultaneous evacuation of air from the packages. Trays are sealed by means of heat-sealing. The sealing temperature for the AMISTYLE BP/CP films varies depending on the equipment operation rate. and lies within the range of 120 – 150 oC. Take care to prevent the product getting into the film sealing zone, because this may lead to a loss of vacuum. The depth of vacuum should be preset depending on the product moisture content. The depth of vacuum should be reduced for packaging of high-moisture food. The seals must be even and continuous, bearing a clear imprint of the sealing bar, without any signs of burn-through. If the sealing quality is unsatisfactory, check the temperature settings.
4.2.4. Cutting of packages The sealed packages are conveyed for longitudinal and transverse cutting. After that the packaged product may be dispatched for weighing, labeling and storage.
