The operator needs to identify whether product spacing, sensor detection, conveyor slip or seal-jaw timing creates the packaging error.
What the symptom can indicate
Irregular upstream spacing can create errors even when the wrapper motion remains synchronized.
Reflective, dark or low-profile products can be missed by a poorly positioned sensor.
Conveyor slip changes actual product pitch while encoder values appear normal.
Buyer analysis
Follow one product through every timing reference
Record infeed spacing, lug or belt position, detection event, film mark and jaw closure. Identify the first timing relationship that changes.
Challenge the detection envelope
Test smallest, darkest, most reflective and least stable SKUs. Confirm sensor position, background contrast and response at target speed.
Separate upstream starvation from wrapper faults
Track whether the machine receives a valid product for each cycle. Buffering or automatic feeding may be required when upstream release is not repeatable.

Recommended machine paths
Pillow Packing Machine Paper From Top
A horizontal pillow packing machine with film fed from the top, used for regular objects such as biscuits, rice cakes, bread, mooncakes, medicines and daily necessities.
Pillow Packing Machine Paper From Bottom
A bottom-film horizontal pillow packing machine for soft, long or loose products such as towels, paper towels, dried noodles, chicken rolls, sausages and soft sweets.
Reciprocating Pillow Packing Machine
A reciprocating horizontal pillow packing machine for products that need controlled end sealing, stable cutting and flexible film handling.

Verify the correction under normal variation
Run the corrected process with normal product, material and utility variation. Confirm reject rate and pack quality before making the new setting a standard.
