Foreword
This Standard replaces GB/T 11115-1989 Low density polyethylene resin, GB/T
11116-1989 High density polyethylene resin and GB/T 15182-1994 Linear low density
polyethylene resin.
Compared with GB/T 11115, GB/T 11116 and GB/T 15182, the main differences of this
Standard are as follows.
- Combined GB/T 11115, GB/T 11116 and GB/T 15182 into one standard;
- In addition to hygienic standard, all normative references in Chapter 2 were
changed as dated references;
- Added Chapter 3 Classification and designation;
- In 5.1, deleted the requirements of “the particle size shall be (2〜5)mm in any
direction” in 3.1 in the original standard; and changed “without mechanical impurity”
into “without impurity”.
- Added “Sample preparation” in the table in Chapter 5 Requirements;
- Replaced “cleanliness (colored particle)” with “granular appearance” in the table in
Chapter 5 Requirements;
- Added “because the application field of each resin is different, the injection molding
sample proprieties can be different from that of compression molding sample” in
6.2.2. The specific prepare method of each resin is shown in Table 1 to Table 7;
- Adjusted the blow molding process of LLDPE film and LDPE film; and deleted
“reduced diameter of film” in 6.2.3;
- Specified two test methods for “fish-eye” in 6.10;
- Re-specified the test method for “strip” in 6.11;
- Added provisions on the shelf life of polyethylene resin in Chapter 9.
This Standard was proposed by China Petrochemical Corporation (Sinopec Group).
This Standard shall be under the jurisdiction of Petrochemical Plastic Resins Product
Branch of National Standardization Technical Committee of Plastic (SAC/TC 15/SC 1).

Polyethylene (PE) resin
1 Scope
This Standard specified the classification and designation, requirements, test methods,
inspection rules, product labelling, packaging, transportation and storage for polyethylene
(PE) resin.
This Standard applies to ethylene homopolymer OR copolymer that takes ethylene and
other 1-olefin as monomer AND polymer that contains additives.
This Standard does not apply to ultra-high molecular weight polyethylene AND colored,
filled, modified, enhanced polyethylene resin AND masterbatch pellets.
