00:00:05

on store shelves we often see

00:00:08

goods in plastic trays. Today we

00:00:11

will tell you how they preserve the freshness and

00:00:14

taste of your products.

00:00:17

To make such a tray you need to use

00:00:20

polypropylene as a basis. This is a type of

00:00:23

food plastic and

00:00:27

its particles are called polypropylene

00:00:31

granulate.

00:00:32

Through pipes, the granulate enters a

00:00:35

special dispenser system where

00:00:37

it is mixed with with a special additive,

00:00:40

this recipe will make the future tray

00:00:43

durable at any temperature

00:00:46

[music] the

00:00:52

finished mixture must be thoroughly dried

00:00:55

so that the dried granules do not crumble and

00:00:58

create dust; the pipes have smooth

00:01:00

bends, like in a water park; it is

00:01:03

through them that the material enters

00:01:06

production;

00:01:07

first, green dye is supplied to the system using vacuum pumps

00:01:13

then all the components go into these

00:01:16

ovens where they are melted to a liquid

00:01:19

state, the

00:01:21

hot mixture of plastics and dye

00:01:24

falls on the calender and the rollers and

00:01:26

is rolled out into a green film, a

00:01:29

transparent barrier layer is applied to it,

00:01:32

this is the main protection, it will not allow oxygen to pass through

00:01:36

and it will increase the shelf life of

00:01:38

products

00:01:39

when two layers the films are connected together,

00:01:42

it is convenient to examine it under a microscope,

00:01:45

our barrier layer is a thin black

00:01:48

stripe on the right, the result is a

00:01:51

high-tech material that

00:01:53

will allow you to deliver fresh meat to the

00:01:55

farthest corners of the country, all that

00:02:00

remains is to wind our miracle film

00:02:03

onto the receiving drum,

00:02:10

the roll is packaged and a

00:02:13

unique barcode is glued to

00:02:16

it the entire history of the product is encrypted

00:02:19

from granules to the finished tray, the

00:02:23

next stage is a thermoforming workshop

00:02:26

to make trays from polypropylene film

00:02:29

and it needs to be heated again in a thermal

00:02:33

cabinet, it becomes soft and pliable

00:02:36

[music]

00:02:39

then hot plastic is fed to the

00:02:41

forming section here with the rest of the

00:02:44

molds the heated film is pressed and

00:02:47

gives it the appearance of trays

00:02:49

[music]

00:02:51

for fresh meat, trays are designed with

00:02:53

stiffening ribs between the product and the

00:02:56

surface of the tray, there should be

00:02:58

a gap so that the gas mixture circulates around the meat pieces,

00:03:03

see how the surface at the top of the

00:03:06

tray shines, the protective film gives it a shine,

00:03:13

now the trays need to be cut out

00:03:16

ready the products are picked up by a manipulator

00:03:19

with vacuum suction cups,

00:03:20

he puts them in neat piles on the

00:03:24

receiving table, the

00:03:26

remaining film is sent for

00:03:28

recycling,

00:03:29

these scraps and used trays can be

00:03:32

melted into a new film, this is how

00:03:36

waste-free production works, the

00:03:39

trays are ready, but it’s too

00:03:41

early to pack the products in them, first they must

00:03:44

go through another important stage line in the

00:03:47

adhesive napkins,

00:03:50

fresh meat during storage releases meat

00:03:53

juice so that it stays fresh longer, you

00:03:55

need to collect this juice,

00:03:59

so a special absorber napkin is inserted into each tray;

00:04:02

it not only

00:04:04

absorbs the juice but also maintains an ideal

00:04:07

environment inside the package

00:04:10

[music]

00:04:12

so as not to use glue, the napkin

00:04:14

is soldered to the masonry Ultrasound

00:04:18

at the end of the line, each tray undergoes

00:04:21

computer control

00:04:22

only high-quality trays are worthy of

00:04:25

storing food,

00:04:30

now you can put meat in them

00:04:34

[music]

00:04:40

so that your raku is fresh on the

00:04:42

packaging lines, a special mixture of gases is pumped into the packaging,

00:04:46

they do not allow the meat to oxidize, this is another

00:04:50

level of protection such a tray will reliably

00:04:53

cover delicious pieces and keep them for

00:04:56

you in their original form.

00:05:00

Today you saw how

00:05:02

packaging for a delicious dinner is born from plastic granules. Speaking

00:05:04

of dinner, perhaps it’s time for

00:05:08

us to have some food
