European Standard - food transport pp woven bag (EN277)
The European standard by the European Committee for Standardization section 120 (relief food transportation bags) Technical Committee (CEN/TC120) formulation, the secretariat of the Committee by the Netherlands Standardization Institute (NNI) as.
This standard is in accordance with EU Council (CEC) requirements developed by a series of relief food transport bags standard.
The standard alternative to EN277: 1989.
The latest European standards should be adopted in October 1995 released the same document or recognized as a national standard, and, in conflict with the standards of national standards, should be no later than October 1995 repealed.
In accordance with the European Committee for Standardization / European Committee for Electrotechnical Standardization (CEN / CENELEC) internal rules, the following States are obliged to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
The European standard specifies the general characteristics of polypropylene woven bags, requirements and test methods.
The European standard is applicable to fill up to 50 kg of quality for food aid transportation of polypropylene woven bags.
This European Standard contains the other publications out of date and not obsolete reference terms. Such reference standard applied to the appropriate body part, such publications are listed below. For obsolete references, the amendment only if the press or the revision of this part of the standard should be the ultimate use of any such publication or revised edition of this amendment. The terms of reference are not outdated and are using the latest version of the publication.

Information about this file can be members of the European Committee for Standardization was the third national units.
This standard, use the following definition:
Note 1: Other terms used in the bag, paper bags were part of EN26590-1 and are thermoplastic flexible film bag to be defined in EN26590-2. Most of these terms can also be used for polypropylene woven bags.
3.1 polypropylene woven bags: polypropylene textile fabric made from the container, at least one end of the closure, may be used for other soft materials lining combine to provide the necessary filling and commodity distribution chain performance.
Note 2? Since then, the European standards body used in the "bag" the term refers to both polypropylene woven bags.
3.2 layer (P1y): the formation of woven polypropylene bags wall organization (tissue).
3.3 Triangular fold (gusset): longitudinal edge embedded in bags inside the folds.
4 General Characteristics
Polypropylene woven bags made from the 4.1.1.
4.1.2 bags should be made of one or more layers, in accordance with EN1086, can be equipped with liner.
4.1.3 bags for flat-type or triangular pleated.
4.1.4 Tile empty bags should be rectangular.
4.1.5 has been filled bag sealing shall be designed to prevent product leakage during transport.
4.1.6 for the bag and the bags sealed (not including liner) of the material, in addition to natural materials, shall be in accordance with
Article 5.7.3 of the UV linear. These materials according to their structure for the bag to be tested.
4.2.1 If necessary, the air bag size should be chosen so that the size of bags after filling line 1SO3676 volume under the unit load size.
4.2.2 Tolerance bag supply and demand should be agreed.
4.2.3 bag size and tolerance should be ordering the contract.
4.2.4 Note the size of bags, size and size measurement mark shall be in accordance with EN26591-2.
Note: Although the EN26591-2 applied to thermoplastic flexible film bags, polypropylene woven bags, but also apply. However, for some forms of polypropylene bags can not use the EN26591-2. 1SO 6591 will be the third part of the International Organization for Standardization Technical Committee 122, Sub-Technical Committee 2 (bags) (1SO/TC122/SC2) formulation.
4.3 Food Compatibility
And food contact bags should be consistent with the European Commission (CEN) member states apply the legislative requirements of such bags.
5 Testing methods and testing requirements
5.1.1 Sampling should be conducted in accordance with EN27023:
Note: EN27023: 1992 Table 1 for the unit selection, EN27023: 1992 Table 2 apply to each selected unit in the choice of bags.
5.1.2 Sampling should be prepared for side air bags of the day sent.
5.1.3 For re-sampling should be conducted in accordance with EN27023.
Such as sampling or testing of the accident must be re-sampling procedures should be in accordance with EN27023 requirements for new samples. However, unless otherwise agreed, such as the former can be selected from the same unit.
If for other reasons, must be re-sampled, then the procedures followed should be as close as possible EN27023 requirements.

5.7.2 Test procedure
Application of B-type fluorescent UV test lamp. Test duration shall be 144 hours (only 6 days). +60 ℃ test cycle should be the next 8 hours and irradiated with ultraviolet +50 ℃ 4 hours condensation conditions alternated.
5.7.3 UV-test eligibility criteria
Test, measured the fracture strength should be at least 50% of the original breaking strength.
Bags for side identification signs and custom signs.
7 test reports
Test report should include the European standards in accordance with the description of all tests, and should at least include the following information:
(A) the name and address of the supplier;
(B) the contract or purchase order number;
(C) sampling date, location and description;
