Manufacturing of agri stretch film
Poliflex's offer in stretch film for hay bales is POLISTRETCH-AGRI
This is an agricultural stretch film for hay bales. The film has the same characteristics as industrial stretch film, but the addition of an additive guarantees perfect preservation of the packaged product up to 12 months.

USEFUL TIPS FOR A GOOD PRESERVATION OF THE PRODUCT
DO NOT PACK WHEN THE WEATHER IS VERY HUMID OR RAINY.
The plots of land should be carefully rolled and mowing should be carried out at a height of between 5 and 7 cm to reduce the risk of contamination of the silage with soil carrying clostridia.
ATTENTION: the first mowing is usually the most contaminated.
If a storage period of 12 months is foreseen for the first cutting, a 6-layer pack is recommended and the dry matter percentage must be over 50%.
A dry substance over 40% is normally recommended.
If this is not possible and is expected a storage period of 12 months, 6 re-coverings are preferable, or 4 re-coverings using the product within 4/5 months after the storage.
If the storage includes periods with high ambient temperatures, it is advisable:
6 coatings per dry substance equivalent to or less than 40%.
4 coatings per dry substance over 40%.
If storage does not involve periods with high temperatures, it is advisable:
6 coatings for dry substance between 30% and 35%.
4 coatings for dry substance between 35% and 40%.
Do not pack the product below 30% of dry substance
Optimum dry substance selection in relation to the product to be packed:
If grasses predominate, dry substance between 40% and 45%, if legumes predominate, dry substance greater than 45%.

OPERATING INSTRUCTIONS
The manufacturer guarantees the integrity of the packaging for 12 months, only if the following conditions are met:
1. THE ROLLS MUST REMAIN IN THEIR ORIGINAL CONDITION UNTIL THE MOMENT THEY ARE USED.
2. KEEP THEM AWAY FROM HEAT SOURCES AND DIRECT SUNLIGHT.
3. APPLY THE FILM WITH A MINIMUM OF 4 OVERLAPS.
The covering must be between 50% and 55% of the previous band.
If it were lower, there would be 3 layers of film at some points in the package.
Each lap of film covers a part of the layer laid on the previous lap.
The covering percentage is determined by the ratio between the two speeds.
The film stretch must be between 50% and 65%: not lower so that there is sufficient clamping force, not higher so that the film is not weakened too much.
ATTENTION
The stretching of the film results in a significant decrease of film width (about 20%).
This means that: a 50 cm wide reel becomes 40 cm wide after stretching.
Therefore, the progress per lap must be equal to or less than 20 cm.
1. THE MOST ADHESIVE SIDE OF THE FILM (THE OUTSIDE SURFACE OF THE FILM) MUST BE PUT IN CONTACT WITH THE BALE.
2. STORE THE BALES ON THE FLAT FACE AND FORM STACKS WITH A SINGLE OVERLAPPING ROW.
3. AFTER WINDING THE BALE, SECURE THE FREE END BY INSERTING IT INTO THE COIL UNDERNEATH.
4. BALE STRINGS MUST BE MADE OF POLYPROPYLENE OR HIGH DENSITY POLYETHYLENE.
5. AVOID ABRASIONS, TEARS, CUTS AND BREAKS OF THE FILM WRAPPED ON THE BALE.
N.B. Past experience has shown that the use of round balers with a variable chamber guarantees a better product result through variable pressure control during bale making, unlike fixed-chamber round balers that do not have this mechanism, often leaving a poorly compressed core and an external pressure too high
