FIELD: process engineering.
SUBSTANCE: claimed process comprises the making of the first and second wraps of three-seam pack. The first wrap includes the first product and is composed of the first wrap of sheet material. The latter is sealed to make the tube over the length of the first lengthwise sealing line and is provided with the first crosswise sealing line on its both opposite ends. The second wrap includes the second product and is composed of the second wrap of sheet material. The latter is sealed to make the tube over the length of the second lengthwise sealing line and is provided with the second crosswise sealing line on its both opposite ends. Claimed process includes also the placing the tubular blanks side by side. The common crosswise sealing line is made on one or both opposite end parts. The latter extends through both end parts of the first and second wrap blanks to define the separable sealing line between the first and second crosswise sealing lines.
EFFECT: easy and safe separation of the pack wrap.
