1 Scope
This document specifies the requirements related to dimensional, mechanical, and optical characteristics
of thermoplastic films and tubes used during the manufacture of silage and designed to last at least one
year for protecting fodder.
It specifies a classification for the durability of silage films and the test methods referred to in this
document.
This document is applicable to transparent, black, white or coloured (e.g. black/white) thermoplastic
silage films based on polyethylene, ethylene copolymer, EVOH and polyamide.
These films are intended for covering bunker silos, silage tubes or silage clamps for preserving forage.
They protect the forage and preserve it from rain and air. These films are not intended to cover bales
piles (e.g. straw bales and hay bales).
This document does not apply to silage films obtained by sealing two or more films in machine direction.
This document also provides guideline for installation, use and removal conditions of silage films. It also
provides guideline for the conventional useful lifetime, as well as rules that allow evaluating the
remaining use potential in the event of a failure before the normal end-of-use date.

4 Types and use
The different types of silage films are given in Table 1.
Table 1 — Types of films
Type Characteristics
SA Film or tube with a nominal thickness ≥ 90 μm
SC Film with a nominal thickness ≥ 35 μm
used as lining in combination with a type SA silage film
SD-PA Film or tube with a thickness ≥ 90 μm
having at least one coextruded layer made from polyamide resins as gas barrier
SD-EVOH Film or tube with a thickness ≥ 90 μm
having at least one coextruded layer made from EVOH resins as gas barrier
SE-PA Film with a nominal thickness ≥ 35 μm
having at least one coextruded layer made from polyamide as gas barrier used as
lining in combination with a type SA silage film
SE-EVOH Film with a nominal thickness ≥ 35 μm
having at least one coextruded layer made from EVOH as gas barrier used as lining in
combination with a type SA silage film
5 Material
Silage films in accordance with this document are usually manufactured from:
— low density polyethylene (PE-LD), linear low density polyethylene (PE-LLD) and their blends;
— ethylene vinyl acetate copolymers (EVAC) and their blends with PE-LD or PE-LLD;
— ethylene butyl acrylate copolymers (EBAK) and their blends with PE-LD or PE-LLD;
— gas barrier polymer, e.g. EVOH or polyamide.
The product shall be suitable for mechanical recycling as a PE fraction, according to the design for
recycling specified in Clause 12.
Recycled content in the film shall be verified with ratio of post-consumer plastic recyclates and/or pre
consumer plastic recyclates following a controlled blending model according to ISO 22095.
6 Durability
The durability of silage films is characterized by the class C0, C1 or C2. This classification, given in Table 2,
is depending on the duration of exposure of the film to an artificial weathering using xenon-arc lamps
according to 8.5, which induces a decrease of the value of tensile strain at break equal or less than 50 %
of the initial value.
The class of durability shall be declared by the manufacturer/supplier.
Table 2 — Resistance to weathering classification
Class Minimum duration of exposure
h
a
C0 140
C1 1 400
C2 2 100
a
For Type SC and SE film, only.
For C1, corresponding to a duration of natural exposure of 12 months for a film used in a climatic
zone ≤ 130 kLy/year . For C2 corresponding to a duration of natural exposure of 12 months for a film
used in a climatic zone between 131 kLy /year and 160 kLy /year and of 18 months for a film used in a
climatic zone ≤ 130 kLy /year .
Other light sources may be used provided that a correlation between the test results obtained with these
light sources and these obtained after a natural exposure can be demonstrated. This may be useful when
the durations of the exposure to xenon-arc lamps as specified in Table 2 are too long. Details of these
methods are given in Annex A.
In case of dispute between different parties, the choice of exposure equipment will be decided by the
parties. If no agreement can be found the exposure to xenon-arc lamps according to 8.5 and the
classification according to Table 2 shall be used.
NOTE An empirical correlation between durability of covering films for greenhouses exposed to artificial
weathering and natural exposure is given in EN 13206.
