1 Scope This European Standard specifies the dimensional characteristics, mechanical requirements and requirements of fitness for purpose of plastics freezer bags used for freezing foodstuffs. It specifies also test methods to check these requirements. It is applicable to plastic bags reserved for household uses to freeze foodstuffs, including the following types:  bags with tie closure, without gusset;  bags with tie closure and lateral gussets;  bags with re-closable features (or with zipper) without gusset. NOTE 1 The above list of types of bags is neither restrictive nor exhaustive. NOTE 2 The application of this European Standard does not exempt the supplier or purchaser from complying with national regulations. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

Figure 1 — Typical freezer bags 4 General characteristics and requirements 4.1 Dimensional characteristics 4.1.1 Effective volume By convention, the effective volume is calculated using Formula (1): Vu = [ Pm2/ (Lm - Pm/2 – Z) -Sm3]10-6
(1) where Vu is the effective volume, expressed in dm3; Lm, is the arithmetic mean, expressed in millimetres, of the two measurements of the length, L, made along the lateral edges on a bag. Pm, is the arithmetic mean, expressed in millimetres, of the two measurements of the width, P, made, at the top and bottom, on a bag. Sm, is the half arithmetic mean, expressed in millimetres, of the two measurements of the width of gusset, 2S, made each side on a bag.
Z = 0 for bags with zipper;
Z = 30 for bags with tie closure (reservation for tying). NOTE The effective volume is not related to the permissible load. 4.1.2 Requirements The supplier shall declare the nominal width Pn and the nominal length Ln, expressed in millimetres. When tested in accordance with test methods as specified in Table 1, the plastics freezer bag shall have dimensional characteristics conforming to the requirements given in Table 1.

4.3 Requirements for fitness for purpose 4.3.1 Suitability for writing The bags shall be provided with a printed area, reserved for writing. The area reserved exclusively for writing shall be greater than 15 cm². The control shall be carried out in accordance with 5.3.1. The printing on the bag and text written with a ball point (greasy ink) shall withstand wiping with a pure cellulose piece of paper after passing through water. 4.3.2 Transparency of the film The bag constituent film shall be sufficiently transparent in order to allow legibility through ten stacked layers (five bags). The control shall be carried out in accordance with 5.3.2. 4.3.3 Water tightness When tested in accordance with 5.3.3, the bags shall remain watertight. 4.3.4 Veil One of the faces of each veil shall not be smooth. 4.4 Suitability for food contact 4.4.1 General The bag constituent materials shall conform to the requirements of all relevant national and/or European regulations.
