1/ Any evidence of rodent or insect infestation shall be cause for rejection of the lot.

2/ The effective closure seal is defined as any uncontaminated, fusion bonded, continuous 

path, minimum 1/16 inch wide, from side seal to side seal that produces a hermetically sealed 

pouch.

3/ Delamination defect classification:

Major - Delamination of the outer ply in the pouch seal area that can be propagated to 

expose aluminum foil at the food product edge of the pouch after manual flexing of the 

delaminated area. To flex, the delaminated area shall be held between the thumb and 

forefinger of each hand with both thumbs and forefingers touching each other. The 

delaminated area shall then be rapidly flexed 10 times by rotating both hands in alternating 

clockwise- counterclockwise directions. Care shall be exercised when flexing delaminated 

areas near the tear notches to avoid tearing the pouch material. After flexing, the separated 

outer ply shall be grasped between thumb and forefinger and gently lifted toward the food 

product edge of the seal or if the separated area is too small to be held between thumb and

forefinger, a number two stylus shall be inserted into the delaminated area and a gentle lifting 

force applied against the outer ply. If separation of the outer ply can be made to extend to the 

product edge of the seal with no discernible resistance to the gentle lifting, the delamination 

shall be classified as a major defect. Additionally, spot delamination of the outer ply in the 

body of the pouch that is able to be propagated beyond its initial borders is also a major 

defect. To determine if the laminated area is a defect, use the following procedure: Mark the 

outside edges of the delaminated area using a bold permanent marking pen. Open the pouch 

and remove the contents. Cut the pouch transversely not closer than 1/4 inch (+1/16 inch) 

from the delaminated area. The pouch shall be flexed in the area in question using the 

procedure described above. Any propagation of the delaminated area, as evidenced by the 

delaminated area exceeding the limits of the outlined borders, shall be classified as a major 

defect.

Minor - Minor delamination of the outer ply in the pouch seal area is acceptable and 

shall not be classified as a minor defect unless it extends to within 1/16 inch of the food 

product edge of the seal. All other minor outer ply delamination in the pouch seal area or

isolated spots of delamination in the body of the pouch that do not propagate when flexed as 

described above shall be classified as minor defects.

4/ Outer packaging shall be free from foreign matter which is unwholesome, has the potential 

to cause pouch damage (for example, glass, metal filings) or generally detracts from the clean 

appearance of the pouch. The following examples shall not be classified as defects for 

unclean:

a. Foreign matter which presents no health hazard or potential pouch damage and 

which can be readily removed by gently shaking the package or by gently brushing the pouch 

with a clean dry cloth.

b. Dried product which affects less than 1/8 of the total surface area of one pouch face 

(localized and aggregate).

5/ If doubt exists as to whether or not the sealing equipment leaves an impression or design 

on the closure seal surface that could conceal or impair visual detection of seal defects, 

samples shall be furnished to the contracting officer for a determination as to acceptability.

6/ Applicable to form-fill-seal pouches only.

7/ The initial examination shall be a visual examination of the closed package. Any suspected 

visual evidence of stress cracks in the aluminum foil (streaks, breaks, or other disruptions in 

the laminated film) shall be verified by the following physical examination. To examine for 

stress cracks, the inside surface of both tray-shaped bodies shall be placed over a light source 

and the outside surface observed for the passage of light. Observation of light through the 

pouch material in the form of a curved or straight line greater than 2 mm in length shall be 

evidence of the presence of stress cracks. Observation of light through the pouch material in 

the form of a curved or straight line 2 mm in length or smaller or of a single pinpoint shall be 

considered a pinhole. Observation of ten or more pinholes per pouch shall be evidence of 

material degradation.

 B. Methods of inspection.

(1) Seal testing. The pouch seals shall be tested for seal strength as required in a, b, or 

c, as applicable.

 a. Unfilled preformed pouch seal testing. The seals of the unfilled preformed pouch 

shall be tested for seal strength in accordance with ASTM F 88, Standard Test Method for 

Seal Strength of Flexible Barrier Materials. The lot size shall be expressed in pouches. The 

sample unit shall be one pouch. The sample size shall be the number of pouches indicated by 
PCR-E-018

inspection level S-1. Three adjacent specimens shall be cut from each of the three sealed 

sides of each pouch in the sample. The average seal strength of any side shall be calculated 

by averaging the three specimens cut from that side. Any average seal strength of less than 6 

pounds per inch of width or any test specimen with a seal strength of less than 5 pounds per 

inch of width shall be classified as a major defect and shall be cause for rejection of the lot.

 b. Pouch closure seal testing. The closure seals of the pouches shall be tested for 

seal strength in accordance with ASTM F 88. The lot size shall be expressed in pouches. The 

sample unit shall be one pouch. The sample size shall be the number of pouches indicated by 

inspection level S-1. For the closure seal on preformed pouches, three adjacent specimens 

shall be cut from the closure seal of each pouch in the sample. For form-fill-seal pouches, 

three adjacent specimens shall be cut from each side and each end of each pouch in the 

sample. The average seal strength of any side, end or closure shall be calculated by averaging 

the three specimens cut from that side, end or closure. Any average seal strength of less than 

6 pounds per inch of width or any test specimen with a seal strength of less than 5 pounds per 

inch of width shall be classified as a major defect and shall be cause for rejection of the lot.

 c. Internal pressure test. The internal pressure resistance shall be determined by 

pressurizing the pouches while they are restrained between two rigid plates. The lot size shall 

be expressed in pouches. The sample unit shall be one pouch. The sample size shall be the 

number of pouches indicated by inspection level S-1. If a three seal tester (one that 

pressurizes the pouch through an open end) is used, the closure seal shall be cut off for 

testing the side and bottom seals of the pouch. For testing the closure seal, the bottom seal 

shall be cut off. The pouches shall be emptied prior to testing. If a four-seal tester (designed 

to pressurize filled pouches by use of a hypodermic needle through the pouch wall) is used, 

all four seals can be tested simultaneously. The distance between rigid restraining plates on 

the four-seal tester shall be equal to the thickness of the product +1/16 inch. Pressure shall be 

applied at the approximate uniform rate of 1 pound per square inch gage (psig) per second 

until 14 psig pressure is reached. The 14 psig pressure shall be held constant for 30 seconds 

and then released. The pouches shall then be examined for separation or yield of the heat 

seals. Any rupture of the pouch or evidence of seal separation greater than 1/16 inch in the 

pouch manufacturer’s seal shall be considered a test failure. Any seal separation that reduces 

the effective closure seal width to less than 1/16 inch (see table II, footnote 2/) shall be 

considered a test failure and shall be classified as a major defect and shall be cause for 

rejection of the lot.

 C. Packing.

(1) Shipping container and marking examination. The filled and sealed shipping 

containers shall be examined for the defects listed in table III. The lot size shall be expressed 

in shipping containers. The sample unit shall be one shipping container fully packed. The 
PCR-E-018
