Change you form element like this
#foreach($subitem as $sub)
<div class="row">
<div class="col-md-4">
<input type="checkbox" name="subitem[{{$sub->id}}][id]" value="{{$sub->id}}"> {{$sub->subitem_name}}
<div class="col-md-4">
<input type="text" name="subitem[{{$sub->id}}][qty]" value="{{$sub->qty}}}" class="form-control" placeholder="Entire Qty">
{!! $errors->first('qty','<p class="help-block">:message</p>') !!}
</div>
</div>
#endforeach
Loop the $request->subitem like this
`
public function update(Request $request, $id)
{
foreach($request->subitem as $key=>$row)
{
$items = new Itempacking;
$items->batch_id = $request->batch_id;
$items->sub_id = $row['id']
$items->quantity = $row['qty'];
$items->save();
$items='';
}`
